4 Title Distributed I/O Modules (DIO) and

PLC Firmware

Description I/O that is distributed around the application or integrated

with the controller. You can install DIO modules locally in the same

chassis as the processor. Through the use of I/O communication networks,

you can also distribute I/O in locations remote from the processor, closer

to the sensors and actuators, reducing your wiring costs. Having the

freedom to monitor and control I/O across an I/O link means you can select

I/O products from a variety of platforms that include a variety of

integrated termination solutions. DIO modules can be located on the machine

close to sensors and actuators, controlled from a safety PLC. A distributed

safety I/O module continuously monitors its internal functions to make

certain that it is functioning and available if a safety demands is placed

on the system. It also provides valuable detailed diagnostic information to

the machine operators and maintenance personnel making troubleshooting

easier and thereby improving overall machine utilization.

5 Title Glucose Engine

Description The Glucose Engine (GE) is a device used to monitor the glucose

count every five minutes. This data is provided to Host Interface (iPhone).

The glucose engine system consists of three components: the Sensor, the

Transmitter, and the Glucose Engine Receiver module. The Transmitter is a

reusable device that snaps into the Sensor Pod and wirelessly sends glucose

information measured by your Sensor to the Glucose Engine Receiver This raw

data is processed by the Algorithm module to get Glucose data and then the

raw value and the engineered value are stored in on-board non-volatile

memory. GE allows a user to view glucose engine module allows a user to

view stored records, read alert conditions, provide calibration data etc.

Apart from being responsible for initialization of Glucose Engine, it also

acts as an interface to know the current state of the Glucose Engine.

Requirement of this project was to implement the communications interface

as a series of host (currently iPhone) or test commands that can be sent

to/from the host (iPhone) to the glucose engine over the glucose engine's

UART serial interface.

Responsibilities - Requirement analysis, creating design documents

- Implementation of

Identify Device Preferences and Settings (IDPS) process over UART serial

communication

between iPhone and

Glucose Engine using iAp protocol.

- Implementation of

Authentication process over SPI between GE and Authentication Co-processor

using iAp protocol

7 Title System Services

Description Provides following different middle-ware services:

Data Manager: Data Manager provides the service to applications

to set/get the information to/from database. This

module uses database interface for database operation.

Polling Services: Polling Service provides timer services

scheduled at user specified interval which provides polling

mechanism for registered handler. This service provides two

types of timer :

1. Repeat Timer: calls handler repeatedly after specified interval expires

till the application is active.

2. One-shot Timer : calls user handler only once after specified interval

expires.

An application will register its handler with Polling Service and request

for scheduling its handler on specified timer interval.

Service Manager: Service Manager registers and initialize all the

basic services i.e. Data Manager, Process Life Manager and all resident

services on system boot-up. It also supports run time registration and

launching of a service. It also notifies that a service has started or

stopped. This service manager uses D-bus rather than binder which is used

by Android's Service Manager (provides access to only Android Framework's

services).

Plugin Manager: Android does not has any application framework to

manage loading/unloading of the plugins. Plugin Manager load all the

plugins which are required on system start-up by default.. It also

load/unload a specified plugin or plugins from a specified directory.

Logger Service: Android does not provide persistent logs. Logger

Service maintains all the logs(Android's Main, Radio, Event, Systems and

kernel logs) at one consolidated location in a NAND. This service starts

at boot-up time. This service reads /dev/log, /proc/kmsg, and /dev/main,

/dev/event, /dev/radio devices and writes to their file on NAND. For fast

writing and NAND longetivity mmap approached is used. It also provides

interface for log retrieval. Log retrieval functionality provides a log

viewer tool to see the run time logs like Android's Logcat.

Task Manager: Task manager processes application's task

asynchronously. Task manager registers application's tasks into a queue

then processes all task s sequentially.

Libraries: Created own containers, string, database, thread, task,

stream, file, mobile's application layer.
