摘要:
A mobile device includes one or more electronic circuits that control the operation of the device. The electronic circuit can be connected to a power source by a switch that can be maintained in the open position when the device is being shipped and stored prior to use. The act of taking the mobile device out of the package can include manipulating the mobile device to cause the switch to close connecting the electronic circuit to the power source to begin operation. In accordance with some embodiments, the switch can include a magnetic switch that is maintained in the open position by a magnetic component in the packaging and becomes closed when the mobile device is removed from the packaging. In accordance with some embodiments, the switch can be maintained in the open position by a packaging insert and becomes closed when the package is opened removing the insert.

The invention relates to a modular power output stage for controlling several electric axle drive motors of multi-axle machines, especially machine tools. The invention is characterised in that the several output stage modules (1, 2, 3), which are adapted in terms of their power to correspond to the particular motor that they control, are mounted on a common cooling body or on individual cooling bodies (10), said cooling body or bodies being situated on a level forming or defining an assembly level. The cooling body or bodies (10) have mechanical provisions for different power variants of the output stage modules (1, 2, 3) at each point and elements (5, 6, 7) are provided for the coded contacting of at least the input terminals of each of the output stage modules (1, 2, 3). The terminals of each output variant of the output stage module are situated spatially differently.

An apparatus for regulating voltage and power in a computer system is disclosed. The voltage and power regulation is performed by voltage regulation circuitry on a voltage regulator module (200). The voltage regulator module (200) is a detachable unit which interfaces with the motherboard (340) through a socket connector (335). The socket connector (335) has a fixed pin definition which allows a variety of voltage regulator modules (200) programmed to regulate voltages and power at different levels to be implemented on the motherboard (340).
摘要:
A field programmable circuit board (11) provides a set of sockets (12, 14) for receiving electronic components, a set of connector pins (16, 18) for providing external access to the board and an array of field programmable interconnect devices (24) (FPIDs). The FPIDs are buffered, multiple port cross-point switches (74) that may be programmed by a host computer to selectively connect terminals of the components mounted in the sockets to one another or to the external connector pins (16, 18). Signal buffers (76) within the FPID ports can be programmed to provide various types of buffering and logic operations on the signals routed by the FPIDs. Each FPID buffer also samples and stores data indicating states of the buffered signals over several system clock cycles for subsequent read out by the host computer (57).
