A wireless link provides an extension to cable television signals for a television receiver that does not have access to a coaxial cable. Analog and digital cable channels are processed and transmitted over the wireless link. Security of the signal is provided by transmitting encrypted data and decrypting at the receiving node. The conditional access encryption inherent in the data can insure communication security or encryption may be performed at the transmitting node.

An electrode device is for microwave coagulation therapy disclosed in which the direction of its electrode tip can be controlled by operation in its proximal region. The device comprises: a handpiece provided with a rigid hollow support shaft extending toward a distal end, a movable support provided at the distal end of the support shaft and carrying thereon an electrode, a coaxial cable which is connected at its proximal end to a coaxial connector and extending through the support shaft and connected in the movable support to the electrode, wherein: (a) the movable support comprises one or more links each surrounding the coaxial cable and longitudinally connected to the distal end of the support shaft so that the movable support can be bent and stretched in a single plane, and (b) the electrode device comprises a resilient stiff member fixed at one of its end to the deflection side of the most distal one of the links composing the movable support and extending through the support shaft and so connected at its proximal end to a control section of the handpiece that the resilient stiff member can be pulled and pushed back at the proximal end of the handpiece.

A coaxial cable connector includes a connector body, a contact chamber, a copper sleeve, and an observation window opening. A central contact bore is formed inside the observation window opening and an insulation layer is set between the central contact bore and the contact chamber. The central contact bore has a notch formed in a side thereof close to the copper sleeve to receive a core conductor of the coaxial cable to insert therein. The central contact bore also has a stop wall that prevents the core conductor from extending beyond the central contact bore. An insulation block covers the central contact bore, and a window opening bolt is set in engagement with and thus closes the observation window opening to force a projection of the insulation block to depress the core conductor to engage the central contact bore for electrical contact therebetween.

A security device protects information handling systems from theft with a reduced footprint at the information handling system by interfacing a key receptacle with a lock hook through a flexible member, such as a coaxial cable. Rotation at the key receptacle by a key translates through the flexible member to the lock hook so that the lock hook rotates to a locked position in a lock body integrated with the information handling system chassis. The flexible member avoids or reduces leverage placed on the lock body through the security device.
