Open Source Instruments Inc. (OSI) designs and manufactures instruments for scientific research. Most of our customers work in neuroscience and high energy physics. We provide software to control and read out the instruments we sell. Our software is free and runs on Linux, MacOS, and Windows. Most of our revenue comes from sales to institutions and private companies, but we occasionally receive, grants from the SBIR programs of the NSF, NIH, and DoE.
For neuroscientists, we design and manufacture wireless, implantable sensors and stimulators. Our sensors provide high-fidelity biopotential monitoring and allow the measurement of spreading depolarizations in freely-moving, cohabiting animals. Our implantable stimulators provide radio-controlled electrical and optical stimulation. Our data acquisition software is free and provides automatic event detection and translation into standard data formats.
For high energy physicists, we manufacture opto-mechanical metrology devices. Our Boston CCD Angle Monitor (BCAM) has been deployed in large particle detectors such as ALICE, and accelerators such as HIE-ISOLDE. More BCAMs will be installed in the up-coming PIP-II accelerator. Our Direct Fiber Positioning System (DFPS) is a new product we are developing for astronomers in collaboration with Texas A&M Univeristy, and with funding from the NSF.
Sub-Cutaneous Transmitter (SCT): Telemetry devices for implantation in small animals. Many configuration options: mass 1.6 g to 14 g, low-frequency cut-off 0.0 Hz (DC) to 20 Hz, high-frequency cut-off 20 Hz to 640 Hz, input dynamic range 30 mV to 300 mV, 1 to 4 channels, lead thickness 0.5-0.7 mm, lead length 20-260 mm, depth or surface electrodes. Configuration-dependent operating life 5 to 500 days.
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.
Electrode Interface Fixture (EIF): A connector with leads and electrodes designed to be cemented to the head of a small animal and mate with one of our HMTs.
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): A wide-angle, wide depth of field camera that provides compressed video synchronous to ±0.1 s with telemetry recordings. Provides night-day programmable, dimming and brightening white and infrared illumination.
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.
Direct Fiber Positioning System (DFPS): A telescope-mounting fiber positioner for astronomical spectrography. Piezeo-electric tubes packed on a five-millimeter pitch place the tips of optical fibers on the images of celstial objects.
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.
Blood Pressure Monitor (BPM): An implantable blood pressure sensor compatible with our telemetry sytem. Connects to a catheter, precision ±0.4 mmHg (50 Pa) at 128 SPS.
