Abstract: An improved device for indicating and measuring small variations in the resistance of a living body is disclosed which utilizes a central processing unit to digitally process sensed body resistances and drive a resistance-indicating display while compensating for the effects of component aging, component tolerances and component temperatures. The device includes an automatic calibration circuit that is automatically activated on each powering up of the device to measure and store measurement values for a plurality of synthesized body resistances that are used to form a compensation model against which sensed body resistances are, subsequently compared for automatic adjustment of display driving measurement values.

Abstract: A storing and transporting system for compact discs (“CD's”) for recorded audio materials and related accessory materials such as notebooks or booklets comprising an outside case of flat, clamshell configuration defining two storage areas, and one or two box-like disc containers of similar configuration to be nested in the storage areas and each having a tray-like body for holding a stack of discs in flexible storage envelopes. Guides and partitions in the case define the two storage areas and hold the stored items snugly therein, and the containers have removable retainers for holding a selected number of disc envelopes therein. Integral recessed latches hold the covers releasably in closed positions, and the case and the container are sized to receive and hold preselected numbers of discs and booklets of related materials so as to be highly versatile in use, and are provided with convenient label areas.

Abstract: An apparatus for reducing distortion during recording in a tape recorder of the type including a recording head which includes an electrically grounded, electrically conductive member in light contact with a coated surface of the recording tape provided adjacent the recording head. With this structure, excess electrons present on the coated surface of the tape after recording are removed.

Abstract: A long-term storage container including a box-like titanium receptacle having a titanium primary cover and sealed by a seal ring of malleable precious metal clamped between the cover and the receptacle, with titanium/ceramic valves in the cover for use in exhausting air from the receptacle and replacing it with argon gas, with titanium/precious metal back-up plugs sealing the valves after the air has been replaced. A titanium secondary cover is bonded to the receptacle by a titanium weld, reinforces the seal by the primary cover, and has a cuttable integral metal wall for ease of opening, and an inner titanium container is disposed in the receptacle with elongated, resiliently flexible ribs in its walls engaging similar ribs on the adjacent walls to provide cushioning against crushing and shocks.
