A control system automatically determines the presence of an auxiliary control. The system includes a controlled device and a main control. The controlled device includes a main control input and an auxiliary control input. If an auxiliary control is present, a discernible non-zero default signal is supplied on the auxiliary control input of the controlled device, when no inputs of the auxiliary control are asserted. This advantageously allows for the verification of correct assembly (i.e., dete...

A modem using digital subscriber line (DSL) provides high speed access over a copper plant. The DSL modem exchanges management information to a terminating multiplexer using a proprietary protocol, thus enabling reliable, fast access to networking resources.

A housing body with a card-retention capability includes a wall that has an outer surface and an inner surface. The outer surface is formed with an elongate card-receiving recess that has a recess bottom. The outer surface is further formed with a first cover-restricting flange that extends from a front end of the card-receiving recess and that cooperates with the recess bottom to form a cover-receiving slot, and a second cover-restricting flange that extends from a rear end of the card-receivin...

A parallel processor is provided that includes integrated debugging capabilities. The processor includes a pipelined processing engine, having an array of processing element complex stages, and input and output header buffers. A debug system is provided that, when triggered, may put some or all of the processing element complexes into a debug mode of operation. When a complex is in debug mode, examination of internal stages of the component circuits of the complex may occur, in order to facilita...

A driving tool includes a handle having a tubular surrounding wall defining a torch receiving compartment. A front end wall is disposed at a front end of the surrounding wall, and has a drive shaft extending outwardly of the torch receiving compartment. The front end wall is formed with a lamp receiving hole offset from the drive shaft and in communication with the compartment. A torch is received removably in the torch receiving compartment, and includes a tubular torch housing with front and r...

A bicycle can have jumping capabilities by providing a spring-biased auxiliary frame directly below the primary frame, and mounting the drive sprocket on the auxiliary frame. The person riding the bicycle can transfer his weight from the bicycle seat to the foot pedals on the drive sprocket so as to lower the auxiliary frame. When the person shifts his weight back onto the seat the auxiliary frame is rapidly raised by the mounting springs, such that the auxiliary frame forcibly strikes the main ...

A driving tool includes a transparent handle, a drive shaft, a ratchet mechanism, and a torch. The handle has a tubular outer casing formed with open front and rear chambers that are isolated from each other. The drive shaft has a connecting end which extends into the front chamber, and a drive end which extends forwardly of the outer casing. The ratchet mechanism is mounted in the front chamber, and is connected operably to the connecting end such that the ratchet mechanism is operable to permi...

A driving tool includes a handle, a drive shaft, and a torch. The handle has a tubular outer casing and a transparent front cap mounted integrally and securely on a front end portion of the outer casing so as to establish a watertight seal therewith. The outer casing confines a receiving chamber with a rear opening, and has an internally threaded rear end portion. The drive shaft is fixed to the front cap, and extends forwardly therefrom. The torch is received removably in the receiving chamber,...

The present invention comprises a novel level switch which may be employed to detect liquid levels within a process vessel. The level switch of the present invention is self validating so that manual testing is not required in order to ensure proper operation and switch calibration. The switch of the present invention may be easily introduced into existing process vessel designs as a replacement for prior art level detection switches with minimal or no retrofitting effort being required. The sel...

A positioning operation is performed to acquire a positioning result immediately before or immediately after a photographing instruction is given. GPS positioning is performed in response to a positioning start instruction (half depression of the shutter), after which the photographing instruction is issued. GPS positioning and photographing are carried out in order when an operation (full depression of the shutter) serves as both the photographing instruction and the positioning start instructi...
