Abstract: A system includes a controller for a DC to AC inverter including a processor configured to execute instructions to perform operations including: generating a first pulse for a first phase of a center-aligned PWM signal to alternately activate a first phase switch of a first switch group of the inverter for a first duration and a first phase switch of a second switch group of the inverter for a second duration within a period of the PWM signal; and generating a second pulse for a second phase of the PWM signal to alternately activate a second phase switch of the first switch group of the inverter for a third duration and a second phase switch of the second switch group of the inverter for a fourth duration within the period of the PWM signal, wherein the second duration is different from the third duration during a stall condition.

Abstract: A terminal includes a spine extending along a longitudinal axis from a first end to a second end and extending along a lateral axis, which is perpendicular to the longitudinal axis, from a first edge to a second edge. An attachment portion at the first end provides fixation to an electrical conductor. A contact portion extends from the second end and cantilevers over the spine such that the contact portion is spaced apart from the spine in a direction along a vertical axis which is perpendicular to both the longitudinal axis and the lateral axis. A locking tab extends from the first edge and has a locking tab attachment end which is fixed to first edge and which extends toward, and is aligned with, the contact portion in a direction parallel to the vertical axis. The locking tab also has a free end which flares outward beyond contact portion.

Abstract: An electronic circuit includes a first pin corresponding to a reference signal and a second pin corresponding to an external resistor, the external resistor being connected on a first side to the second pin and connected on a second side to ground. The apparatus also includes a first oscillator having a first frequency loop configured to: receive, via the first pin, the reference signal; receive, via the second pin, a current associated with voltage applied to the external resistor; and lock a first frequency output at a frequency associated with the reference signal. The apparatus also includes a second oscillator having a second frequency loop configured to: receive the first frequency output; scale the frequency of the first frequency output; and lock a second frequency output at the scaled frequency of the first frequency output.

Abstract: A resistor-assembly includes a substrate, a heater, a resistor-element, and conductive-leads. The substrate is formed of a ceramic-material. The heater heats the resistor-assembly. The resistor-element is formed of an ion-conducting material that overlies the substrate. The conductive-leads are formed of a catalytic-metal that are in communication with a gas and in electrical contact with the resistor-element. The resistor-element is characterized by a resistance-value influenced by an oxygen-presence in the gas when the resistor-element is heated by the heater such that a resistor-temperature is greater than a temperature-threshold.

Abstract: A method for assignment of vehicle control includes receiving route data indicating a route between a starting location of a vehicle and a destination location, and determining an optimal vehicle configuration for the route based on a target vehicle speed and a hybrid torque split. The method further includes receiving a driver requested torque value and determining a passive pedal torque value based on the route data and vehicle powertrain data. The method further includes selectively assigning control of the vehicle to a vehicle system or to a driver of the vehicle based on the driver requested torque value and the passive pedal torque value.
