Abstract: A mounting bracket for releasably mounting an article such as a sign or picture frame to a substantially flat surface such as a wall. The bracket has an adhesive disc securely attached to one side of the bracket and the opposite side of the adhesive disc has a releasable adhesive face for attaching to the wall. A tool inserted into the mounting bracket applies a rotative force to the mounting bracket for applying a shear force to the releasable adhesive face which causes the adhesive face to release from the wall. The mounting bracket is releasably mounted to a sign, which allows easy installation and removal of the sign from the wall.

Abstract: Activated clotting time (ACT) tests detect blood clotting time based on the viscosity changes of a test sample, using a ferromagnetic washer lifted to the top of a test chamber and then dropped from the top via gravity; a drop time greater than a preset threshold value indicates clotting of the test sample. Blood samples which have high levels of heparin usually produce very weak clots that may easily be destroyed by the lifting movement of the washer. But if the clot threshold is set low to detect the weak clots, false detections occur during early testing cycles when activators are not fully suspended during the mixing cycle. Improved algorithms for lifting the washer and adjusting over time enable accurate detection of weak clots.

Abstract: Embodiments of a USB cable extension system is disclosed for delivering power to a device via a USB connection. The system can include converter circuitries to convert a voltage supplied via a USB connector to a different voltage for transmission over a power transmission wire and to convert a voltage received from a power transmission wire to a different voltage to be supplied to a USB connector connectable to a device to be powered.

Abstract: A roller pump including a drive shaft, a motor, a roller head assembly, a stator housing, and an occlusion adjustment assembly. The drive shaft is coupled to the motor. The roller head assembly includes a hub, a slide body, and a roller. The hub is mounted to the drive shaft, and maintains the slide body and the roller. The stator housing forms a raceway receiving surface. The occlusion adjustment assembly includes an actuator knob, an actuating structure, and a ground shaft. The actuating structure interfaces with the slide body, and thus the roller, with rotation of the knob. The ground shaft supports the knob and is rotationally isolated from the drive shaft. A user and optionally a control system can adjust occlusion while the pump continuously delivers a fluid medium.

Abstract: A stamp die assembly for a self inking stamp in which the die plate having printing indicia thereon is easily removable from the die frame. There is a movable latch on the die plate that is received by a catch or slot in the die frame to lock the die plate to the die frame. By pushing on a push button the catch is moved from the locked position to the unlocked position in which the latch is released from the catch. A spring returns the latch to the original or locked position.

Abstract: A stamp die assembly for a self inking stamp in which the die plate having printing indicia thereon is easily removable from the die frame. There are at least two locking bars on the die frame that engage in locking relationship at least two positioning tabs on the die plate. Locking tabs on the positioning tabs engage in a locking relationship the locking bars to securely attach the die plate to the die frame. The locking tabs are flexible so that when a force is applied to them they can be flexed to an unlocking position thereby releasing the die plate from the die frame.

Abstract: The Automobile Ignition Powered, Momentary Push Button switch Controlled, Cellular Phone Jammer with Emergency Capability is made for use in prevention of cellular phone use in commercial vehicles and for teen drivers while the vehicle is in operation.

Abstract: A method of manufacturing a hand stamp by assembling a stack of individual stamp pegs. The pegs are attached to each other by tabs and slots so that the individual pegs can be easily separated from each other. A sheet of rubber like material has characters on the sheet. The individual characters are separated from each other by a small bridging portion of the rubber like material. The sheet of rubberlike material is then adhesively attached to the top of the stack of stamp pegs. The individual pegs can then be separated from each other and re-assembled to form a hand stamp with the desired characters forming words or other information.

Abstract: A multi-position latch mechanism is provided for a subsurface aircraft ground servicing chamber formed by a pit having an upright interior wall and a pit lid seat disposed atop the pit. A pit lid is provided which, when closed, rests upon the pit lid seat. The latch mechanism includes a catch member depending from the pit lid adjacent the upright wall of the pit. The catch member is mounted to the pit lid for rotatable movement relative thereto. A latching member is mounted on the upright interior pit wall and has a plurality of vertically spaced teeth that face the catch member. The catch member has a hook facing the latching member. The hook is alternatively engageable with each of the teeth, depending upon the extent to which debris on the pit lid seat holds the pit lid off of its pit lid seat.
