  • Patent number: 12006140
    Abstract: A refuse vehicle includes a chassis, an energy storage device, a vehicle body, an electric power take-off system, and a hydraulic component. The energy storage device is supported by the chassis and is configured to provide electrical power to a prime mover. Activation of the prime mover selectively drives the refuse vehicle. The vehicle body is supported by the chassis, and includes an on-board receptacle for storing refuse therein. The electric power take-off system is positioned on the vehicle body, and includes an electric motor configured to drive a hydraulic pump to convert electrical power received from the energy storage device into hydraulic power. An amount of electrical power at least one of received by and provided to the electric motor is limited by a controller to control an output characteristic of the hydraulic pump. The hydraulic component is in fluid communication with the hydraulic pump and configured to operate using hydraulic power from the electric power take-off system.

  • Publication number: 20200296977
    Abstract: The present invention relates to apparatus and methods for assembling food products. More particularly, the invention relates to apparatus and methods for associating foodstuff and liquid with a base. Foodstuff may include food items such as meats, vegetables, cheeses, amongst others. Liquids include those food items that have a low viscosities (e.g. sauces, dressings, oils), high viscosities (e.g. peanut butter, frosting), and anything in between. A base can be anything on which foodstuff or liquid may be associated (e.g. bread, cake, cookies, pizza dough, a bowl in which to place foodstuff).

  • Publication number: 20050114713
    Abstract: One aspect of an embodiment of the invention relates to a method for substantially mitigating identity fraud. The method comprises (1) transmitting a password to a centralized entity for verification of the subscriber, where the password is unique to a subscriber being a party to a financial transaction. The password is compared to stored information at the centralized entity. If a match is detected, a certificate is provided by the centralized agency. The certificate authorizes access to credit data of the subscriber.

  • Patent number: 5248900
    Abstract: A PWM output device using time-multiplexing to create multiple time-bases from a common time-base counter and thereby supporting multiple PWM output signals capable of having different periods and duty cycles. A circulating timer shifts to provide various fundamental time-bases to each PWM module, which sets and resets its PWM output upon a proper state determined by a looping state counter. When the state counter reaches 0, it causes the circulating counter to increment and the state counter to reload. As the circulating counter shifts, it generates a plurality of values to be used as the fundamental timebases for the PWM modules. Each PWM module comprises a time-base match unit, a duty cycle control unit, and an output control unit. The time-base match unit in each individual PWM module determines when the time base produced by the circulating counter is valid by comparing its preset valid state value with the state value from the state counter.
