  • Patent number: 11445704
    Abstract: A sound button devices, systems, and methods for sound buttons capable of emitting sound using less power, greater sound transmissibility, and/or greater resistance to damage and that allow for training both non-humans and humans to communicate more effectively than previously possible In typical embodiments, the sound button may comprise a shell, a switch operably connected to a printed circuit board (“PCB”), a button cap assembly operably coupled to the shell, the button cap assembly comprising a button cap having at least one recess, the at least one recess having a hole; and a speaker facing toward the button cap, where, when a force is applied to the button cap, the button cap and the speaker move together to actuate the switch, thereby causing the speaker to emit a sound.

  • Patent number: 8683094
    Abstract: A method for enhancing data transmission efficiency in a data transmission system having a host, a subsystem and a transmission interface, utilized for the host to transmit and receive a data from a memory of the subsystem via the transmission interface includes steps of the host outputting a query command to the subsystem via the transmission interface for querying available memory utilization of the subsystem; the subsystem outputting a return message to the host via the transmission interface for indicating the available memory utilization according to the query command; and controlling data transmission from the host to the subsystem according to the return message.

  • Publication number: 20120104609
    Abstract: A discrete circuit component has copper block electrodes and that utilizes a simple copper substrate as the basis for the component. The component is made by providing an electrode separation hole preformed in the main substrate. The electrode separation hole results in a simple fabrication for the construction of the discrete component product. With the presence of the electrode separation hole, two solid blocks of copper automatically come into shape for each fabricated device at the final phase of production when each device is cut loose from the main production matrix.
