Abstract: In one embodiment a carry device includes a first inner carry pouch made from a first material and an outer bounding pouch or layer made from a second material defining at least one cavity therebetween. An access port may include a release and inflation actuator and provides volumetric access to the at least one cavity allowing passage of a pressurizing atmosphere or temperature effecting medium, or combination thereof. A sealable access is provided, and a common pressure is applied to an outer uniform-pressure region of a non-rigid or rigid item being carried thereby preventing damage and crushing thereof through high contact pressure gradients. In another embodiment handles are inflatable to aid sealing the inner carry pouch and provide a comfortable grip.
Abstract: A push-button keyboard is located on the dashboard of a truck for unlocking a rear access door to rear cargo space in the truck. Selected ones of the keys are sequentially operated in accord with a given combination generating a signal which throws a lock bolt as by means of a solenoid. A first timer prevents operation of the lock unless the combination keys are operated within a first given time interval. A second timer automatically releases the solenoid operated lock bolt after a second given interval of time has elapsed to relock the access door in the event it has not been opened. The signal to the solenoid operated bolt itself is frequency coded to inhibit introduction of unauthorized signals in an unauthorized attempt to operate the lock.
