  • Publication number: 20220283641
    Abstract: In one example, an electronic device may include a touch panel defining an input surface having an input region and a display panel disposed below the touch panel. The display panel may visualize a virtual keyboard including a set of virtual keys. Further, the electronic device may include a haptic array module disposed below the display panel. The haptic array module may include a first actuator disposed below the input region corresponding to a first virtual key of the set of virtual keys. Further, the electronic device may include a controller in communication with the haptic array module to trigger the first actuator to generate a haptic output at the input region in response to an activation of the virtual keyboard.

  • Publication number: 20140253033
    Abstract: A system and method for controlling the operation of an electrically operated vehicle. The system comprises a digital commutation system for charging electric vehicle batteries. That system includes an electromagnet, an electromagnet status sensor, and a controller. The electromagnet is coupled to a crankshaft and configured both to receive a current from the batteries and to supply charge to them The electromagnet status sensor is configured to detect a status of the electromagnet and the controller is configured to control coupling of the electromagnet to batteries based on the detected electromagnet status as well as to monitor the current received by and the charge supplied from the electromagnet. The method includes supplying a current to the electromagnet, producing a electromagnetic field in the electromagnet winding, pulling the electromagnet core into the winding, and then collapsing the electromagnetic field, capturing and storing the charge corresponding to the collapsed field.

  • Publication number: 20050198399
    Abstract: Embodiments of a device authorization system authorize a connection device to be communicatively coupled to a processing system. One embodiment comprises a communication system interface configured to receive authorization from a network administrator device for a processing system to communicatively couple to a connection device; a card detector to detect the presence of the connection device when coupled to the processing system; and a card power switch configured to receive an authorization signal when the processing system is authorized to communicatively couple to the connection device, and configured to supply power to the connection device only when the authorization signal is present and when the card detector detects the presence of the connection device.

  • Patent number: 6094033
    Abstract: A battery state of charge (SOC) detector for rapid charging and method each provide an efficient means for formatting, charging, and recharging batteries of various types and ratings. The detector determines the SOC of a battery to be charged and then selects an optimal charging signal profile based on the SOC determination. During the charging process, the detector can continuously monitor battery SOC in order to select appropriate waveforms for the charging signal. The charging signal is a pulse width and amplitude modulated current, voltage or power waveform with the amplitude and pulse width of each charging pulse being selected based upon the detected battery SOC. Predetermined battery parameters, such as equivalent circuit capacitance and resistance, electrochemical overcharge, maximum battery temperature, and maximum battery internal pressure, among others, also can be compared with monitored values during the battery charging process to control the charging signal in order to avoid battery damage.
