Abstract: Device for secure distance measurement being a prover (P) or a verifier (V) comprising: a receiver (R3) configured to receive a receiving signal (RS) with a transmitted message (M) encoded therein, wherein the transmitted message (M) contains a verifying bit sequence (VBS), wherein a bit of the transmission message (M) is transmitted in the transmission signal (TS) by a pulse with a pulse modulation parameter with two pulse states, and a decoder (R2) configured to decode the verifying bit sequence (VBS) from the transmitted message (M) encoded in the receiving signal (RS).

Abstract: An inflatable hand splint for treatment of patient with arthritic or stroke paralyzed wrists employs a pliable soft vinyl two ply sheet enclosing at a first end an air bladder. The air bladder has an external air valve for attaching to a hand operated air pump. The second end of the soft sheet extends downwardly along the underside of the patient's wrist and is strapped to the patient's forearm with a pair of straps engaged by hook and loop material. A front end of a hard plastic support member is inserted between the fingers and palmer portion of the patient's hand. The rear end of the support member is located below the soft pliable sheet and is also strapped to the patient's forearm. The air bladder is inserted under the patient's finger tips and inflated to move the fingers away from the palmer region.
