Abstract: Systems and methods are provided for locking equipment exposure settings. The system includes a safety interlock device coupled to an access point of a barrier and equipment enclosed thereby. The safety interlock device is configured to suspend a normal operation of the equipment while in an open state and allow the normal operation while in a closed state. The system includes an access point control device configured to allow a user to select among exposure settings for the equipment corresponding to operability of the equipment, and to, by a processor: control the equipment to operate in accordance with a selected exposure setting, determine whether the safety interlock device is in the open or closed state, automatically lock the selected exposure setting if the safety interlock device is in the open state, and automatically unlock the selected exposure setting if the safety interlock device is in the closed state.

Abstract: A security control module for controlling access through a passageway of a secure control area, comprising an ultra-wideband transceiver configured to establish an ultra-wideband transmission with a mobile device and a processing unit configured to determine a first distance between the security control module and the mobile device by processing signal properties of the ultra-wideband transmission. The security control module is configured to receive a second distance from a further security control module arranged at a spacing distance apart, the second distance being indicative of a distance between the further security control module and the mobile device. The processing unit is configured to determine the relative position of the mobile device with respect to the security control module based on the first and second distance.

Abstract: Exercise equipment comprises a weight stack configured to oppose a given exercise motion through a cable and pulley system and an elongated connector connecting the cable to a weight stack. The elongated connector comprises a first threaded portion located proximate to the weight stack and a second portion located distal from the weight stack. The first threaded portion is engaged with the weight stack and has a diameter that is greater than a diameter of the second portion such that an operator can visually determine whether the connector is fully engaged with a threaded receptacle in the weight stack.

Abstract: A central monitoring station is linked to a plurality of remote terminals, such as payment terminals at a plurality of parking facilities. A two-way communication system enables communication between a customer who is remote from the central monitoring station and an attendant at the central monitoring station. The communication system may also allow the attendant to manipulate each remote terminal to collect data or troubleshoot or override the function of the terminal.

Abstract: A preferred embodiment of a revolution counter tool and method employs an adapter shaft with input and output ends coupled in-line between a driven part and a driving part, and an intermediate portion between the input and output ends that is coupled to a rotary encoder and encoder circuit. A memory counter circuit maintains a count of turns and increments of the driven part by the driving part, and a reference setting circuit sets a reference setting of the memory counter circuit when a count is to be taken. The device body has a first portion mounting the adapter shaft with the rotary encoder, an intermediate housing containing the memory counter circuit, and a second portion at a distance from the first portion and of a sufficient mass that acts to orient the device body to a gravity-determined position as a reference position.

Abstract: An apparatus for detecting intrusions into spaces of various kinds such as apartments, offices, lockers, and the like by either authorized or unauthorized persons apparatus monitors a specific portal for intrusion occurrence events using an intrusion sensing unit, which communicates intrusion occurrence information to a remote, and possibly hidden monitor unit. The monitor dynamically counts the number of valid intrusion occurrence signals received from the sensing unit and stores the same in non-volatile memory. The number of intrusions stored in memory can be displayed on a display means at the monitor unit, which, in a simple embodiment would take the form of a single, seven segment light emitting diode (LED) display. In addition, the number of intrusions stored in the non-volatile memory can only be reset by the input of a unique, coded personal identification number (PIN) signal from an input keypad located on the monitor unit.

Abstract: A toy race track and lap counter comprising a track with adjacent lanes each forming a complete circuit and racing objects which are propelled around the track by pressurized air controllably discharging from separate nozzles in a propulsion tower. Separate air impulse devices are provided for each player for controlling the timing and intensity of each burst of pressurized air against that player's racing object as it passes by the propulsion tower and beneath the nozzles. A plurality of propulsion towers may also be provided which are operably interconnectable whereby simultaneous air bursts are applied at more than one location around the track by each player by manually timing the activation of that player's air impulse device.

Abstract: A damping device is provided for damping momentum in a rotary member to stop it at a desired normally stopped position without any override therefrom, the device including a friction plate moveable against the rotating member at least in the terminal stage of its travel to produce the stopping effect.

Abstract: A lap counter for free running radio controlled toy vehicles includes two edge members which together define a convergent section of track and one or more counting devices on one or both sides of the convergent section of track. Each counting device includes two or more counting stations each of which has an actuating member associated with it positioned to be contacted by a trigger member carried by a vehicle. The actuating members of each counting device are arranged at different heights and connected to a respective one or two indicator arms which indicate the number of laps driven by a vehicle.
