Description
This module is part of a full-fledged Shipment
Management System. In shipping industry, it is common to have labels on parcels
for AIS (automatic identification system). These labels are printed on special
hardware printers called Thermal Printers. These printers are programmed using
vendor specific scripts, which are pure text streams. In order to render same
labels on different type of printers, users must create and manage multiple label
scripts, one for each type. This becomes a tedious job when customers are in
overwhelming number. Thus, this
component was designed keeping in mind following objectives
§
Provide a mechanism to
support different thermal printers from a common script.
§
Ability to import
existing scripts to common storage format.
§
And most important,
enable the product to print on ordinary (cheaper) printers such as laser and
inkjets.

Description
This project serves as a complementary tool of
communication for PACS solution. It facilitates users with point-to-point and
group-communication over IP network in form of Audio, Video, Text, Whiteboard
and file transfer. Each client is capable of establishing a communication
session with other users by using IP address or saved identities. Video uses
generic web cam support and serializes the image stream using a set of
compression techniques. Audio data is also compressed using standard codec
provided by the OS. Default video frame compression is achieved by deploying
Intels JPEG library. Default audio streaming uses Microsofts GSM audio codec.
All network operations use single socket for different type of data, avoiding
the need of multiple sockets for different type of streaming. Each communication
channel operates on a common socket with a unique channel ID and packet
sequencer algorithm. File transfers can be initiated on separate sockets to
avoid overload on main socket in order to achieve smooth operation of video and
audio channels.

Description
Clients of
MAROTECH PACS solution are major university hospitals spread over large campus
and branched throughout the country. While the main PACS solution works within
the hospital network domain, need arises on main occasion to provide the users
with the ability of remote access to the PACS archives and database as in local
environment. The best way to achieve it is web. Users connect the web PACS
server using standard IE browser and can start working on any system without
the need of preinstalled software. All software components required on client
system are packed and distributed with a custom installer component designed
specially for this task. This component downloads itself on client machine when
the user connects for the first time to the web server. It is the
responsibility of this component to perform any install/updates on client
system. This component is distributed with VERISIGN signature. Web PACS client
software is a full-featured PACS viewing and reporting system implemented using
COM components. It connects to the web server using HTTP and interfaces with
the DB using XML. It can retrieve and send information about work list items,
reports, studies. Images retrieval from the image server is possible in two
ways viz. standard HTTP fetch and Socket connection. HTTP fetch is preferred in
situation where firewall security is a concern. On the other hand socket file
I/O provides a faster way of retrieving patient images on client machine.
Most of Server part is written in ASP with ADO & XML. Imaging server is a
IIS component written in VC++ which provides HTTP delivery of images with
selectable encryption. Another part of imaging server is a win32 application,
which provides means of image transfer on a TCP/IP Socket.

Description
This is a generic utility to distribute &
update software suites over Internet. This software is designed in two parts.
1.
Server - This is the
connection point for the web distributable clients. It is basically a HTTP
service based on IIS. It enables the users to download the client software,
which in turn connects to the server and performs differential
installation/update for the selected software component(s). The server streams
the software package and package information in XML format, which include file
sizes, directory structure, registry settings, and version information and file
date and time stamps.
2.
Client - It is
implemented as a COM component, which enables it to be downloaded from the web
service by directly connecting to the Installation server using MSIE browser.
It eliminates the need to preinstall the software. It also enables the client
to be integrated into user applications to perform customized updates. When
connected, it downloads the package information for the given software package
from the configured server and creates a cross checked list against the
components installed on the client system. It then downloads the differential
components and performs the relative installation for the components. This can
also install a software package from the scratch. It supports a batch of pre
and post installation task, which can be performed, which includes folder
mapping, folder creation, component registration, registry entries, running
specified programs with specified parameters etc. The package can be
categorized into components and sub-components, which can be individually
selected for installation/update. The update check can be configured to occur
timely or can be triggered manually. It supports un-installation of the
software package using standard windows interface.

Description
This project is a key component in PACS suite of
MAROTECH Inc. The objectives of this module are to store, manage, query,
retrieve and distribute the huge amount of PACS image data. It is a pure distributable system. It uses
SQL Server (can support other databases as well) to store and index the image
file paths and header information. Actual physical files are stored on a variety
of storage media depending on the importance & longevity of the image
files. Its functional layers are as follows
·
Connection Point and
Tran-receiver This layer is where client
software establishes a communication point with the storage system. It verifies
the authenticity of the client and issues a 128-bit communication handle to the
client for further interactions. It also negotiates for the mode of transfer of
the image data, total number of images and specific image identifiers. Image
header information is exchanged in XML format between the client and server.
The trans-receiver module sends or receives the image data and information via
the negotiated mode of transport. It can be OS/Network file copy, Socket based
transfer and HTTP based upload/download.
·
Encryption / Decryption
Layer Each file transfer is
intercepted by this layer. Incoming images for storage are decrypted in this
layer. The mutual encryption/decryption of data is performed based on the 128
bit dynamic communication handled issued by the connection point layer. It ensures
the security of images.
·
Image indexing and
storage database This is employed
using Microsoft SQL Server. This database stores the link to physical link to
the image file and generic image information such as dimensions, color depth,
grayscale shifting parameters, rotations etc. A unique image identifier
character string identifies each image.
·
Compression /
Decompression Engine & Term Manager
Image data is stored in a variety of formats depending on the patient history,
image history, and modality. Images can be stored in Raw mode (uncompressed),
short-term (lossless compression), mid-term (lossy compression with medium Q
Factor) and Long-term (Compression with small Q Factor). As the image ages, the
compression is shifted from raw to long-term. This function is automatically
managed based on the configuration, by this layer. After a configurable period
of time, the images are sent on a backup system and are removed from the
storage system except for the image information.
·
Physical Storage System This is where the image data is stored. It
consists of different storage systems such as RAID, NAS and DVDRAM.

Description
The client is involved in production of fiberglass
using state of the art technologies controlled by advance DCS systems. All the
data related to these processes are stored on a central server hosted on
Solaris OS. This data is required on windows system for analysis and report
generation. Need arose for an interface which could automatically transfer data
at scheduled time intervals to Windows and then the data could be stored in the
SQL Database after being extracted from the flat data buffers coming from
real-time systems. A peer was developed on the Solaris OS using C, which
accepts incoming requests and replies with blocks of information from the
real-time database. The clients on the Windows Environment retrieve the data
and extract the desired information and store it on the SQL Server. This
process eliminated the huge time and manpower required to transfer and filter
the data manually. These are the features of this project - Cross platform
