  • Publication number: 20170028288
    Abstract: An absorption towel disclosed here illustrates a towel arrangement, which will effectively protect the workout equipment from damage or stains, and protecting the user from contacting disease-causing germs. The absorption towel comprises a fabric section and a pocket section. The fabric section is configured to cover a body contact component of a workout equipment. The pocket section is defined at an upper portion of the fabric section, where the pocket section is configured to conform to an end surface the body contact component. The fabric section is configured to absorb secretions from body of a user, and to prevent the surface of the body contact component from damages due to the contact of the user's body with the body contact equipment.

  • Publication number: 20060188776
    Abstract: A high capacity battery including terminals on a terminal-bearing face thereof, and a plate member coupled in spaced-apart relationship to the terminal-bearing face to define a coolant gas flow space therebetween including a peripheral gap for coolant gas communication with an exterior environment of the battery. One or more motive coolant gas drivers is mounted on the plate member and arranged for effecting flow of coolant gas through the coolant gas flow space and the peripheral gap, and the motive coolant gas drivers are electrically coupled with the terminal-bearing face for powering of such drivers. Such high capacity battery can be substituted for a conventional battery in a battery-powered apparatus such as a forklift vehicle, to provide extended use operation as a result of the on-board thermal management capability of the battery.

  • Publication number: 20060181449
    Abstract: A vehicular traffic surveillance Doppler radar system and method for use of the same are disclosed. In one embodiment, the system comprises a modulation circuit portion for generating modulated FM signals. An antenna circuit portion transmits the modulated FM signals to a target and receives the reflected modulated FM signals therefrom. A ranging circuit portion performs a quadrature demodulation on the reflected modulated FM signals and determines a range measurement based upon phase angle measurements derived therefrom.

  • Publication number: 20050162829
    Abstract: A thermal management system for fast charging and subsequent heavy use operation of high-capacity batteries. The thermal management system includes at least one motive driver arranged to impinge air on the terminal and strap structure of the high capacity battery. The terminal and strap structure in a specific aspect of the invention is protectively shrouded by a cover including a main top surface member having air inflow openings therein and a circumscribing wall depending downwardly therefrom and provided with gas egress openings along its medial and end portions. Such cover allows a high flux flow of air therethrough, for high efficiency cooling of the battery during fast charging and subsequent heavy use operation.

  • Publication number: 20050090982
    Abstract: An enhanced police Doppler direction sensing radar detects possibly dangerous traffic conditions during certain vehicle maneuvers such as U-turns and returns to travel after roadside stops. By monitoring a host or primary vehicle speed, speed transitions, transmission state (e.g. gear selection), and the closing vehicle position, range and speed, a number of selectable conditions are detected, resulting in an alert indication to a primary vehicle operator. User preferences and thresholds allow the traffic alert function to be customized according to a primary vehicle operator's desire to suppress alerts in situations which the user does not deem dangerous. The traffic alert function may be automatically triggered under certain detected conditions, or manually initiated when the primary vehicle operator intends to make a driving maneuver.

  • Publication number: 20050062642
    Abstract: A system for processing vehicle speed data for a vehicle is provided. The system includes a front antenna assembly of the vehicle generating a front digital signal, and a rear antenna assembly of the vehicle generating a rear digital signal. A fast Fourier transform system converts the front digital signal into front frequency shift data and the rear digital signal into rear frequency shift data. A patrol speed system matches the front frequency shift data and the rear frequency shift data and generates a vehicle speed for the vehicle.

  • Publication number: 20050046387
    Abstract: A highly efficient fast charger for high capacity batteries and methods for fast charging high capacity batteries. The fast charger preferably comprises a rectified AC input of single or preferably three phases, with an optional power factor corrected input, minimally filtered with high frequency, high ripple current capacitors, which is switched with a power switching circuit in the “buck” configuration into an inductor/capacitor output filter. Metallized film capacitors are employed, to minimize the rectified 360 Hertz AC component filtering while providing transient switch protection and ripple current requirements for the buck regulator, to provide a high current fast charger with substantially improved power factor. High power, high frequency switching with minimized output filter size provides a highly filtered DC output. The fast charger is adapted to be constructed in a modular design for simple maintenance.

  • Patent number: 5875281
    Abstract: Direct current (DC) solid state series wound motor drives for hoist and crane applications. A microprocessor controlled electronic system is employed to control the speed, direction, acceleration and deceleration of a direct current DC solid state series wound motor drive for a hoist or a crane (bridge or trolley). The operation can be via an operator, radio remote, or computer communication link. The system requires a speed and direction command from the operator controls; it then configures the motor and varies the speed while offering certain protection circuits. The DC series wound motor drive includes a DC series wound motor comprising an armature and a series wound field that is supplied with DC voltage power from an external source. The DC voltage power supply can either be generated DC or rectified alternating current (AC). High speed insulated gate bipolar transistor (IGBT) switching elements are provided.
