摘要： An orthopedic back support for displacing a person's weight from the lower area of the spine by providing support for the upper torso and for use with a chair or seat having a seat base and a seat back. A flexible fabric cross piece is connected between vertical axillary support members to provide back support. The cross piece may include vertical channels or sleeves at opposite sides to receive and support the vertical members. The entire unit is portable and when in use facilitates unobtrusive intermittent use and easy ingress and egress from the seat to relieve discomfort after long periods of use. A rib band may be attached to the flexible fabric by means of hook and loop fabric strips such as Velcro to form a detachable connection. A hook strip is disposed on the back of the rib band and is adapted to cooperate with a mating soft loop strip on the forward side of the flexible fabric member which supports the user in a seated position by the combined action of the flexible fabric and rib band. Alternatively, the rib band may be used separate from flexible fabric back support in which case the detachable connection is made between the rib band and the seat back. The connections are such that the force of connection is greater in sheer than in tension.

摘要： A device and system for preventing channel blockage on aircraft voice communication frequencies caused either by the pilot beginning a transmission while someone else is transmitting on the same channel or by a stuck microphone condition. The device includes an arrangement so that one does not interrupt other transmitters having the same device. The present device enforces a reciprocity by use of a subaudible tone which is transmitted. If the tone is detected, the device will not interrupt such a transmission. However, if someone else is not transmitting the subaudible tone, the device can ignore their transmission and operate as though the particule radio channel is available for use. An anti-blocking switch extends between the push-to-talk line as connected to the transceiver and the push-to-talk switch. The single anti-blocking switch may be used to inhibit transmission corresponding to a particular channel being occupied and corresponding to a stuck microphone. A circuit is used to detect activation of the push-to-talk switch twice within a given time period and uses that information to close the anti-blocking switch and allow transmission even on an occupied channel. An audio tone and/or a light is provided to the pilot or other radio operator to indicate that a radio transmission is being inhibited. Present radios may be considered as having transmitter priority, a radio using anti-blocking circuitry will have receiver priority.

摘要： Systems for preventing the operator of an aircraft radio from beginning a transmission while someone else is transmitting on the same radio frequency channel, which is known as "stepping on" the first transmission. In one form, a "step-off" device in accordance with the invention is internally connected to the radio receiver circuitry to sense when a particular selected radio frequency channel is in use. An SCR is interposed in series with the transmitter push-to-talk (PTT) line, and the SCR is gated into conduction only when the selected radio frequency channel is not in use. In another form, a step-off device is retrofitted externally to a aircraft radio, without requiring any modification whatsoever to the basic radio. Operating power for the step-off device is derived from the PTT circuit.
