Abstract: The invention provides a hoof angle measuring device for use on horses. A base is configured to be held against the bottom of a horse hoof and a pivoting arm can then be aligned with the forward edge of the hoof to define the hoof angle. Without physical or electrical contact with the base or arm, an enclosed sensor detects relative angular position between the base and arm. Supporting circuitry also provided in an enclosure accepts signal voltage from the sensor and provides a protected digital display of the measured angle magnitude for the user.

Abstract: A novel probe for recording EMG signals from muscles, in particular intravaginal signals from the pelvic floor muscles (PFM), is provided herein. The probe includes an insertion end having a suction head forming a vessel open at the top with attached electrodes and a distal end for attachment to a means of providing suction and an amplifier.

Abstract: A method and apparatus for measuring differential and absolute concentrations of a selected gas, preferably oxygen, in two flowing gas streams is described. A reference gas and a sample gas in separate gas flow paths are passed at selected temperature, pressure and flow rate over a pair of gas sensors, connected in series with their cathodes or anodes connected together, which produce output signals proportional to the differential selected gas concentration between the sensors and the absolute selected gas pressure in each sensor. The output signals may be amplified and recorded by any conventional means.

Abstract: In monitoring systems for acquiring data about a subject, such as are used, for example, in the medical, scientific and engineering fields, determination of temporal relationships between data acquired from multiple monitoring devices is facilitated by means of an interface unit which interconnects the monitoring devices with tape recorders for storing the data and a computer for processing the data. The interface unit generates various timing and control signals including a time code signal. The interface unit supplies the time code signal to the recording devices for recording simultaneously with the data. The time code signal may be a linear time code (LTC) derived from a video sync signal generated by the interface unit for synchronizing a camera. A sampling clock signal for controlling digitizing of the analog data acquired by the system is derived from the time code signal.

Abstract: The backing of a pile weather strip is scored from the underside thereof at a location between the pile strip and one side edge of the backing to permit the part of the backing between the score line and the aforesaid side to hinge so that the weather strip can be inserted into a T-slot through the opening thereof instead of being slid longitudinally into the T-slot through an open end thereof.
