Abstract: A prisoner restraint system (14) restrains kicking movement of a seated prisoner's legs by restraining movement of the prisoner's feet (94, 96) upward from positions resting on a vehicle floor (44), and by restraining forward movement of the prisoner's feet (94, 96). The prisoner restraint system (14) includes seat belt webbing (82, 86), a seat belt buckle (84), and a seat belt locking tongue (80). The prisoner restraint system (14) has an engaged condition in which the tongue (80) is interlocked with the buckle (84) to secure the webbing (82, 86) across the prisoner's lower legs (90, 92).

Abstract: A system and method for monitoring tread wear, shock absorber performance, balance condition of a vehicle tire, and/or rotation speed of a vehicle wheel, use a sensor to provide acceleration signals. To monitor tread wear, acceleration signals from the sensor determine at least one resonance frequency of at least one of the radial and lateral acceleration of the tire and compares it to at least one stored resonance frequency To monitor shock absorber performance, the amplitude of the Fourier component of the radial acceleration is compared to a stored amplitude value. To monitor a balance condition of a vehicle tire, the sensor provides acceleration signals measured over a specified time duration to determine an amplitude of the Fourier component of the radial acceleration that is compared to a stored amplitude specification balance condition of the tire.

Abstract: A tire and suspension monitoring and warning system consisting of a set of multi-function sensors that monitor and warn of a failure mode. The system monitors and warns for tire imbalance, tire tread wear, and shock absorbers for a tire attached to a vehicle. The monitoring and warning system includes one axial, radial, and lateral acceleration measurement of the wheel to provide acceleration signal sample power. For tire imbalance, signal sample power in the second harmonic of the tire rotational frequency is compared to that of the first harmonic. For tire tread wear, average signal sample power within a second frequency range is compared to a previously stored baseline value. For shock absorber performance, a sum of all frequency components in a second predetermined frequency range is compared to a baseline value.

Abstract: A tire monitoring method and apparatus is provided to predict tire tread separation for a tire on a wheel of a vehicle. This may involve monitoring a parameter of a tire of a vehicle over time and comparing information regarding the monitored parameter (over time) with a reference threshold value of the parameter (over time). The method may also include providing information to a driver based on the comparison. The parameter may be acceleration (axial, radial or longitudinal) along an axis of the tire. The parameter may also be tire imbalance, temperature inside the tire, speed of the tire, load and/or pressure, for example. Information regarding the comparison may be transmitted to a driver if the monitored parameter exceeds the reference threshold value for a predetermined amount of time.

Abstract: Disclosed is a low flow, low Reynolds number cavitating venturi. This cavitating venturi includes an inlet for receiving a liquid at an upstream pressure and an outlet for discharging the liquid received by the inlet at a downstream pressure. The liquid passes through a converging portion having a converging sidewall which extends from said inlet, through a throat portion having a throat sidewall and a diverging diffuser portion having a diverging sidewall. The cavitating venturi provides a substantially stable liquid flow rate independent of the downstream pressure up to a downstream pressure at least as high as 80% of the upstream pressure at a Reynolds number of 60,000 or less.
