Patent number: 12179558Abstract: An ultra low cost electric vehicle heating apparatus, components thereof, and related method are herein described. A driver circuit operates a switching device at an intermediate state between fully-turned-off and fully-turned-on, in a high power dissipation heating mode, to efficiently produce heat energy for heating a passenger compartment, or energy storage system, of an electric vehicle. The driver circuit operates the switching device to have a fully-turned-off state and a fully-turned-on state in a main function mode for a traction inverter or an energy storage system charger of the electric vehicle. The driver circuit is operable to cycle the heating mode and the main function mode for combining such heating and such main function operation of the traction inverter, or the charger, without compromising the operation of the traction motor, or charger, while simultaneously eliminating many of the expensive resistive heating components in use by practitioners of the art.Type: GrantFiled: July 5, 2022Date of Patent: December 31, 2024Assignee: RANCHO DEL I.P.Inventor: Andy Turudic

Patent number: 9559881Abstract: A transceiver system with reduced latency uncertainty is described. In one implementation, the transceiver system has a word aligner latency uncertainty of zero. In another implementation, the transceiver system has a receiver-to-transmitter transfer latency uncertainty of zero. In yet another implementation, the transceiver system has a word aligner latency uncertainty of zero and a receiver-to-transmitter transfer latency uncertainty of zero. In one specific implementation, the receiver-to-transmitter transfer latency uncertainty is eliminated by using the transmitter parallel clock as a feedback signal in the transmitter phase locked loop (PLL). In one implementation, this is achieved by optionally making the transmitter divider, which generates the transmitter parallel clock, part of the feedback path of the transmitter PLL.Type: GrantFiled: September 15, 2008Date of Patent: January 31, 2017Assignee: Altera CorporationInventors: Neville Carvalho, Allan Thomas Davidson, Andy Turudic, Bruce B.

Patent number: 8098787Abstract: One or two Serializer/Deserializer (SerDes) modules are used to measure the time between two pulses with high resolution. A PLL inside a SerDes block is locked to a reference clock and an input signal is passed through a storage element to create a serial data stream that is converted into a parallel data stream by a demultiplexer inside the SerDes. The parallel data is stored in a bit logic unit that compares the parallel data to a second parallel data obtained in similar fashion in another SerDes from a second input signal. The time between the two pulses is then calculated as the number of cycles in the serial data stream that corresponds to the number of bits between the positions of the two events.Type: GrantFiled: December 13, 2007Date of Patent: January 17, 2012Assignee: Altera CorporationInventor: Andy Turudic

Publication number: 20030006842Abstract: Two transistors are coupled in a cascode topology between a load resistor and a first current source. A third transistor is coupled between the cascode transistor output terminal and a second current source. The current provided by the second current source causes a constant voltage drop across the load resistor and consequently a steady offset voltage at the cascode transistor output terminal. When the control transistor in the cascode circuit switches on, the current provided by the first current source provides an additional voltage drop at the cascode transistor output terminal.Type: ApplicationFiled: July 3, 2001Publication date: January 9, 2003Inventors: Andy Turudic, William H.
