Innova has worked on a variety of projects in many different
product markets. Here are some recent examples:
Wireless Pulse Oximeter and Temperature Capsule USB Receiver
For this product Innova worked closely with the customer
starting with the product definition and specification stage.
In this fashion a well optimized solution was designed and
The USB powered receiver device is used to optically activate the
Wireless Pulse Oximeter and Temperature Capsule. Sensor data is
received via a custom RF protocol and transmitted to the PC over the
USB connection. In addition, data is logged locally using a
small-footprint file system.
Battery Powered Wireless Pulse Oximeter
The headband Pulse
Oximeter measures the subjects blood oxygen saturation level, heart
rate and respiration rate. In addition, posture and activity levels
are reported via an on-board accelerometer.
The hardware, firmware, and RF protocol were designed to optimize
battery life. Due to extreme optimization, a run time of 200 hours was
achieved from a small battery even though normal operation requires
pulsing of red and IR LEDs, RF transmission every second, continuous
sensor data collection, and digital signal processing.
The shown two-board set was designed to drive an optical linear array
sensor with variable integration time. The low-noise, low-charge
injection charge amplifier developed for this optical spectrometer
utilized intensive software compensations.
The hardware and the firmware were designed to take maximum
advantage of available resources to achieve a simple, yet powerful,
Customer requirement for PC communication backwards compatibility
was achived after careful examination of the original product.
This board was designed for Worcester Polytechnic Institute's Precision Personnel Locator Project. Included in the
design are OFDM wide band receivers, 14-bit 400MHz ADCs, 200MHz 16-bit
DAC, OFDM transmitter, Giga-bit Ethernet, and Virtex-4 FPGA.
GPS Signal Generator
The PCI card based product is used in a GPS satellite signal
simulator. The same RF signal transmitted by the GPS
satellites covering L1, L2, and L5 bands are generated by the
The BoatNanny is a boat & yacht security product utilizing a 2.4GHz
IEEE 802.15.4 based radio and a Cellular modem. The system monitors
temperature, motion, water level, AC/DC power, and acoustic level.
Alarm messages and command messages are sent via text messages or
email to the boat owner's cell phone.
We have developed many other products in RF, industrial control &
sensing, instruments with embedded microcontrollers, medical devices,
research prototypes, consumer electronics, scientific instruments,
We also develop PC programs that are used in the configuration, calibration,
and application of products that we design.
