  • Patent number: 12294362
    Abstract: An analog input device including at least one mounting panel and a matrix of analog push button assemblies mounted thereon. Each analog push button assembly including an analog pressure sensor including a pressure reception arrangement having an optical sensing sub-arrangement configured to measure an amount of light varied according to a pressure sensed at the pressure reception arrangement and an output terminal for outputting an analog signal corresponding to the amount of light measured, and a plunger element configured to exert the pressure on the pressure reception arrangement. The analog input device may include a multiplexer including an input side coupled to the push button assemblies and an output side; an analog-to-digital converter coupled to the output side of the multiplexer; a processor coupled to the analog-to-digital converter and configured to output a data packet; and a communication interface configured to transmit the data packet to a host computing device.

  • Publication number: 20240013637
    Abstract: The wrist rest may include a base structure; at least two flexible supports extending from the base structure; a vibration assembly supported on the at least two flexible supports in a manner such that the vibration assembly may be spaced apart from the base structure; and a cushion assembly including a cushion disposed over the vibration assembly in a manner so as to conceal the vibration assembly between the base structure and the cushion. The cushion may be secured to the base structure. The at least two flexible supports may be configured to isolate the base structure from a vibrating motion of the vibration assembly. A surface of the vibration assembly directed towards the cushion assembly may move relative to a corresponding surface of the cushion assembly in a manner so as to allow the vibration motion of the vibration assembly to be sensed through the cushion.

  • Patent number: 8612720
    Abstract: A system and method for implementation of MMU assisted data breakpoints for any number of data structures within a program application are provided. For each data structure for which a data breakpoint is desired, two distinct MMU entries are created. One MMU entry has access attributes. The other entry has an interrupt triggering sub-entry. According to the preferred embodiment, access to the second MMU entry causes a page fault.
