Abstract: The load on the communications resources of a cellular telephone system is monitored to detect instances of excess amounts of unused resource capacity. When such instances are detected, a message is transmitted to subscribers via the cellular system offering reduced charging rates for calls initiated in response to the offering message. The subscriber mobile stations are programmed to alert the subscriber to the broadcast of the offering message, after which the subscriber may initiate a reduced rate call. The mobile stations may further be programmed to automatically initiate the cellular call in response to receipt of the offering message, and to thereafter engage in the communication. Monitoring of communications resources external to the cellular system is also made, and an offering message is broadcast by the system in response to detection of excess amounts of unused external resource capacity, in response to which subscribers may initiate calls requesting reduced rate access to the resource.

Abstract: A child seat belt clip having a housing containing preferably two block-type pinch clamps to secure a lap and shoulder belt slid into a housing. Depression of preferably a latch or lever acts to rotate the clamping blocks about their respective axle, allowing the clamping blocks to be rotated up and out of the way for easy insertion or removal of the lap and shoulder belt into or from a slot in the housing. Release of the latch allows springs wound around each axle to rotate the clamping blocks back, and in tight contact with the lap and shoulder belt, thereby securing the lap and shoulder belt against the wall of the housing. Increased force against the clamped belt acts to tighten the clamp against the belt, reducing the possibility of slippage of the lap and shoulder belt through the seat belt clip.

Abstract: Apparatus and methods are described for preventing the penetration of vehicles by narrow objects such as guardrail ends or portions of a guardrail end treatment during a collision. In one embodiment, portions of an ET-2000 guardrail extruder terminal are adapted for improved operation during impacts by attachment of a penetration guard. The penetration guard may also be affixed to other guardrail end treatments or even other suitable highway objects to create an improved safety apparatus. The penetration guard includes a frame and is affixed to the impact head of an ET-2000 guardrail extruder terminal. The frame is greatly collapsible when impacted from a substantially end-on direction. However, when impacted from a direction other than substantially end-on, the frame is substantially non-collapsible and maintains its integrity. The frame includes an outer housing which defines a central opening. The housing is preferably formed of a unitary outer of sheet metal which surrounds the central opening.

Abstract: Responsive to an incoming call made to a primary telephone number subscribing to a call transfer calling service feature, a first switching node queries a data base to retrieve at least one transfer-to secondary number. The first switching node then signals other switching nodes in the telephone network to set up an outgoing legs to each secondary number telephone. The signals transmitted by the first switching node further direct each of the other switching nodes in the network to inhibit the initiation of any call transfer service features associated with the secondary number telephones. The signals may further include a transfer service indicator and a counter identifying the number of prior call transfer which have occurred in connection with the originally received call. If the counter exceeds a given preset threshold, the other switching nodes reject further transfer of the call.

Abstract: Progressive degradation of the osteocalcin present in the blood, serum or plasma samples obtained from a patient is observed in such samples and leads to falsification of the osteocalcin values obtained in a subsequent determination. It has been found that this osteocalcin degradation can be prevented by adding an amount of divalent metal ions, in particularly calcium ions, sufficient to prevent osteocalcin degradation to the sample immediately after it has been obtained or while it is being obtained.
