USB Smart Switch with Packet Re-Ordering for Interleaving among Multiple Flash-Memory Endpoints Aggregated as a Single Virtual USB Endpoint
A dual-mode Universal-Serial-Bus (USB) switch can operate in a normal hub mode to buffer transactions from a host to multiple USB flash storage blocks that are USB endpoints. When operating in a single-endpoint mode, the dual-mode USB switch intercepts packets from the host and responds to the host as a single USB endpoint. The USB switch aggregates all downstream USB flash storage blocks and reports a single pool of memory to the host as a single virtual USB memory. Adjacent transactions can be overlapped by packet re-ordering. A token packet that starts a following transaction is re-ordered to be sent to the USB flash storage blocks before the data and handshake packets that end a first transaction, allowing the second transaction to begin accessing the flash memory earlier. Data can be mirrored or striped across several USB flash storage blocks and parity can be added for error recovery.

Occupant Counter Control Switch for automatic turning on and off electrical appliances in a room
InactiveUS7155317B1Save energyEasy to changeProgramme controlBoards/switchyards circuit arrangementsAlone leftAudio power amplifier
A provided smart switch called Occupant Counter Control Switch, or OCCS, basically comprises of a motion sensor PIR, a photo sensor, an amplifier with band-pass filter, a microprocessor, a digital display, and a relay or triac to drive electrical appliances such as lights. The PIR sensor detects heat from a human body moving across it and generates a distinctive signal that is, unique to each of the two directions, further processed by the microprocessor for counting and thereby controlling the relay. Installed at the entrance of a room replacing the regular switch (see FIG. 1), the OCCS counts up, displaying a digit great than zero, upon detecting a person entering the room and turns on the lights if sensing insufficient ambient light. OCCS constantly energizes the lights during the room is occupied and immediately switches them off upon counting down to zero when detecting the last person exiting the room.
