Abstract:
A system and method for controlling air bag deployment systems based on the presence, position, size, and weight of a person present in an automobile or a child seat present in an automobile is disclosed. The system may include a radar transmitter, radar receiver, and a processor or additionally a weight sensor, a reflector, and a child seat reflector. The transmitter generates and transmits ultra-wide band (UWB) pulses and the receiver generates a receiver signal based on reflected UWB pulses received by the receiver. The receiver signal contains information indicative of the presence, position, and size of a person in the automobile or regarding the presence of a child seat in the passenger seat. The weight sensor generates a weight signal indicative of a weight present in either the passenger side seat or the driver side seat of the automobile. The processor either inhibits deployment or controls the rate of deployment of an airbag based on the receiver signal and the weight signal. Alternatively, the processor compares the receiver signal and the weight signal to a set of predetermined receiver signal profiles and weight signal profiles and controls deployment of the airbag based on matching receiver signal and weight signal profiles.

Abstract:
A receiver (50) is configured to receive a tabbed magazine (100). The receiver (50) includes a receiver well (81) having a slot (82) configured to accept the tab (120) on the tabbed magazine (100). In operation, the tabbed magazine (100) can be inserted into the receiver well (81) without having to rotate the tabbed magazine (100) into the receiver well (81). A magazine catch (63) engages a locking feature in a rib of the tabbed magazine (100) so as to support the tabbed magazine in the receiver well (81). Once the tabbed magazine (100) is empty, the tabbed magazine (100) can be ejected by pressing a magazine release button (61) without the need to rock the tabbed magazine (100) out of the receiver well (81). The magazine release button (61) can be configured to allow the user to eject the tabbed magazine by pressing the magazine release button (61) on either side of the receiver (50). Once a loaded tabbed magazine is placed into the receiver well (81), the user can press a bolt stop button (73) to release a bolt stop (71). The bolt stop button (73) can be configured to allow the user to release the bolt stop (71) by pressing the bolt stop button (73) on either side of the receiver (50).
