DIP switch

Abstract: A switch, switched architecture and process for transferring data through an FCAL switch is disclosed. The switch uses multiple switch control circuits each coupled to one FCAL network and all connected to a crossbar switch. The switch control circuits are coupled together by a protocol bus for coordination purposes. Local conversations can occur on each FCAL loop and crossing conversations through the switch can occur concurrently. The OPN primitive is used to establish the connection before any data is transferred thereby eliminating the need for buffer memory in the switch control circuits. The destination address of each OPN is used to address a lookup table in each switch control circuit to determine if the destination node is local. If not, the destination is looked up and a connection request made on the protocol bus. If the remote port is not busy, it sends a reply which causes both ports to establish a data path through the backplane crossbar switch.

Abstract: An RF switch circuit and method for switching RF signals that may be fabricated using common integrated circuit materials such as silicon, particularly using insulating substrate technologies. The RF switch includes switching and shunting transistor groupings to alternatively couple RF input signals to a common RF node, each controlled by a switching control voltage (SW) or its inverse (SW_), which are approximately symmetrical about ground. The transistor groupings each comprise one or more insulating gate FET transistors connected together in a “stacked” series channel configuration, which increases the breakdown voltage across the series connected transistors and improves RF switch compression. A fully integrated RF switch is described including control logic and a negative voltage generator with the RF switch elements. In one embodiment, the fully integrated RF switch includes an oscillator, a charge pump, CMOS logic circuitry, level-shifting and voltage divider circuits, and an RF buffer circuit.

Abstract: A medical treatment system has medical treatment equipment and a control device that controls the operation of this medical treatment equipment. The medical treatment equipment has an operation control section that controls operation of a therapeutic instrument connected to the medical treatment equipment with respect to a selected single function thereof. The control device is constructed including a hand switch and foot switch. This hand switch and foot switch are provided with mode input sections. Also, the foot switch has an operating switch. The control device is constituted by a selection section that recognizes and selects an operating mode of the items of the medical treatment equipment in accordance with an operating mode signal from a mode input section of the hand switch or foot switch, a switchover section that is switched over such that an on/off signal from the operating switch of the foot switch is transmitted to the items of the medical treatment equipment selected by this selection section, and a display data generating section that generates display data for displaying on a monitor, using as an input signal the on/off condition of the operating switch of the foot switch or the operating mode of the item of the medical treatment equipment selected at the selection section.

Abstract: A scalable high performance ATM cell/packet switch (HiPAS) element for a shared memory switch fabric application. The switch element includes a PAC Bus (Packet/ATM Cell Bus) and the Switch Fabric Controller Bus (SC Bus). The HiPAS switch element receives and transmits the ATM cells/packets through the PAC Bus. The PAC Bus provides independent parallel datapaths for the receive port and transmit port. The PAC Bus provides a unique structural feature to the HiPAS switch element and allows expansion to the switch capacity in a manner similar to a bit-slice processor. Multiple number of HiPAS switch elements can be concatenated to expand the capacity. In the concatenated configuration, the datapaths of the receive port and transmit port are interleaved so that the interconnection remains point-to-point. As the result, all of the switch ports in the switch execute the cell transactions concurrently on the PAC Bus. In addition, each switch fabric port has a dedicated serial port to exchange status information between the switch fabric and the switch port adapter.
