  • Patent number: 10336152
    Abstract: A weight distribution system for dynamically controlling and adjusting the weight load on each axle of a vehicle uses a manifold that is fluid flow disposed between a source of pressured air and the air bags of the vehicle. The manifold allows an individual air bag to be inflated or deflated independently of the other air bags to a desired pressurization depending on either preprogrammed or user input parameters or external conditions. The system can be used to raise and lower the tractor or trailer for tractor and trailer coupling and decoupling. The system can quickly change air bag pressure to try and avoid a rollover. The system can monitor road and weather conditions and adjust the vehicle suspension accordingly. The system can adjust the suspension based on vehicle speed. The system can keep the vehicle at a constant height while loading or unloading. The system can keep track of the weight of the vehicle.

  • Patent number: 8958698
    Abstract: A radio-frequency (RF) remote control (10) has a user interface and transmits an RF signal (11) which designates a device (14) to be controlled and a command for that device. The RF signal is received by an intermediary device (12). The intermediary device, in turn, generates and broadcasts a plurality of high-power IR signals (13A-13F). These signals may be received directly by a controlled device (14A) or may be received indirectly by a controlled device (14B, 14C) after one or more reflections from objects (16A, 16B) and/or room surfaces (18). Thus, reliable control of the devices (14) is obtained even in situations where merely transmitting a typical IR signal may not provide reliable control of the device (14).

  • Patent number: 8737842
    Abstract: The invention relates to embedding data into a luminance output generated by an illumination system comprising a light source and a controller. The controller is configured to embed data by modulating a drive signal applied to the light source with an information signal comprising a shifted base code and a synchronization code. The synchronization code serves to provide synchronization for the receiver, while the shifted base code serves to carry the embedded data. A cyclic phase shift that is applied to a base code to generate the shifted base code corresponds to particular data, such as, for example, light source identification, that needs to be embedded into the luminance output of the illumination system. In this manner, data may be embedded into the luminance output generated by a light source without requiring synchronization of this light source with other light sources.

  • Patent number: 8384250
    Abstract: A system and method for ensuring that a large number of connectors, such as fiber-optic cable-connectors, which are plugged-into connector-receptacles arrayed across a connector-panel, are not intentionally disconnected by an un-authorized user with malicious intent, or accidentally unplugged by an authorized technician who may be trying to manually pull-out a specific connector for testing or other purposes but, inadvertently, could otherwise unplug a neighboring connector because of not being able to clearly see which plug is actually being removed due to the large number of cables that are connected to the panel. The connectors are locked in place by restraining arms which are controlled by solenoids or motors. Each restraining arm can be commanded to release its respective connector, but only when the correct command from a computer is received. The same system and method can be applied to connector-receptacles arrayed on one or both sides of the panel.

  • Patent number: 7843326
    Abstract: The disclosed system provides headgear, i.e., a Firefighter Helmet, with forward illumination that also acts as a personal rescue detection system for quickly finding a downed of lost firefighter. More specifically, the headgear includes a forward illuminating light that has unique characteristics that are easily detected in a smoke filled space by using a handheld photodetector probe that is tuned to the exact characteristics of the light source. The handheld probe has a somewhat narrow directional response to allow a directed search for a downed firefighter or other emergency personnel in a smoke filled noisy environment that hinders normal visual and audible search methods. The handheld photodetector probe produces a unique audio tone that is proportional in volume to the intensity of the exact-characteristics-light-source thus allowing a sweeping motion of the probe to immediately determine the relative direction to a firefighter who is down or requiring assistance.

    Abstract: Light emitting diodes are placed side by side at a front end of the remote control transmitter in a manner that their maximum radiation directions, i.e. radiation directions each giving a maximum radiation intensity, are each inclined at an angle within a range no larger than 5 degrees outwardly of the remote control transmitter 1 and symmetrically with respect to a bisector of a line segment which connects center points of the light emitting diodes. The inclination, within a range no larger than 5 degrees, of each of the light emitting diodes used as light sources for remote control does not cause significant reduction in the radiation intensity. Accordingly, it is possible to widen the transmittable angle within a range no larger than 10 degrees without significantly reducing the radiation intensity at a central portion of the radiation range.
