Active Products

Sub-Cutaneous Transmitter (SCT): Telemetry devices for implantation in small animals. Available with in many versions: mass 1.6-14 g, bandwidth up to 640 Hz, sensitivity down to 0 Hz, dynamic range 30-300 mV, operating life 5-500 days, 1-4 channels, lead thickness 0.5-0.7 mm, lead length 20-260 mm, with depth or surface electrodes.

Head-Mounting Transmitter (HMT): A biopotential sensor that mounts on the head of a small animal by means of a miniature connector, compatible with our subcutaneous transmitter (SCT) system. Accompanied by Electrode Interface Fixtures (EIF).

Implantable Stimulator-Transponder (IST): An implantable stimulator designed for long-term experiments requiring intermittent, short-duration stimulation. Provides pulsed, variable-current electrical stimulation with a bipolar electrode, or pulsed optical stimulation with one of our implantable lamps.

Implantable Light-Emitting Diode (ILED): A variety of implantable lamps for use with our Implantable Stimulator-Transponders (ISTs). We have red, green, and blue Surface-Mount Light-Emitting Diodes, and green and blue Fiber-Coupled Light Emitting Diodes.

Implantable Inertial Sensor (IIS): An implantable accelerometer and gyroscope for recording the dynamics of fish swimming or rodents running.

Animal Location Tracker (ALT): A combined receiver, activity monitor, and location tracker in the form of a platform we place beneath a cage full of animals with implanted SCTs.

Telemetry Control Box (TCB): Sixteen-antenna telemetry receiver, location monitor, and command transmitter.

Animal Cage Camera (ACC): High-resolution camera that provides compressed video synchronous with our SCT recordings to ±0.1 s. Also provides variable-intensity visible and infrared illumination. Does not interfere with our SCT telemetry.

Boston CCD Angle Monitor (BCAM): Survey cameras and point sources for monitoring deformations of large structures, 5-μrad precision, 50-μrad absolute calibration, designed for particle detectors and accelerator alignment. We manufacture all active varieties of BCAM as well stand-alone light sources and long cables.

Wire Position Sensor (WPS): Two-camera wire position sensor to monitor the shape of a long, straight wire, 1-μm precision, 5-μm absolute accuracy, designed for linear accelerator alignment.

Developing Products

Direct Fiber Positioning System (DFPS): A telescope-mounting fiber positioner for astronomical spectrography. Piezeo-electric tubes packed on a five-millimeter grid place the tips of optical fibers on the images of distant galaxies, while spectrometers at the other end of the fibers measure the galaxys' red shift. Funded by the National Science Foundation (NSF) grant 2111936.

Contactless Position Measurement System (CPMS): An optical system for measuring the position and orientation of highly-reflecting metallic objects. Custom-built instruments with optional motorized stages.
