Abstract: Dynamic baselining of current modulation-based talkback from a slave device to a master device in a system such as an electronic blasting system, wherein the dynamic baselining enhances communication integrity under conditions of environmental noise and the like. With a data packet of appreciable length, the dynamic baselining is preferably performed repeatedly on the bytes or words within the packet.

Abstract: A hybrid electronic and electromechanical arm-fire device comprising a moving mechanical element having a safe position and an armed position, one or more pyrotechnic detonators each having an output mounted on the moving mechanical element, a pickup adjacent to the detonator output(s) that is in alignment therewith when the moving mechanical element is in the armed position but is not so aligned when the moving mechanical element is in the safe position, and electronic circuitry including a logic core having an electronic switch. The electronic circuitry may also include an electronic sensor such as a photointerruptor.

Abstract: A safety system for a compartment of a vehicle includes an occupant sensor for sensing an occupant within the compartment of the vehicle, a vehicle-based control, and a wireless transmitter of the vehicle. The control is responsive to the occupant sensor. The control controls transmission by the wireless transmitter. The wireless transmitter may transmit to a receiver located external of the vehicle upon detection by the occupant sensor of the presence of an occupant within the compartment of the vehicle.

Abstract: Firing-readiness diagnostics in an electronic pyrotechnic device such as an electronic detonator or an electronic blasting system thereof. The diagnostics may include a check for any incompatible attached devices, a resistance or continuity check of an ignition element, and/or a capacitance check of a firing capacitor.

Abstract: A safety sensing and/or release system for a closed compartment of a vehicle is operable to detect an occupant within the vehicle compartment. The system may be operable to sense ambient conditions in the vehicle compartment, and may generate a control signal in response to the sensed conditions. The system may actuate indicators to notify operators of the vehicle that there is a person or animal detected in the compartment. Optionally, the system may open the vehicle compartment in response to a detection of an occupant and the sensed conditions. The safety system includes a false trigger protection means that limits or reduces false detections of a person or animal within the compartment.

Abstract: A multiple slave logging device, or “logger” for use in a system such as an electronic blasting system. The logger is able to communicate with multiple slave devices connected to it, and preferably also is able to communicate with a slave device connected individually. The logger preferably utilizes current modulation-based talkback from the slave devices, and optionally may also be adapted to detect the presence of inappropriate slave devices connected to the system.

Abstract: A method of dynamically- and continuously-variable rate asynchronous data transfer, such as for use in an electronic blasting system, may employ a device that transmits data including synchronization bits and bits conveying other information, and a device that ascertains the rate of transmission of the synchronization bits and receives the bits conveying the other information at the ascertained rate of transmission.

Abstract: A safety sensing and/or release system for opening a closed compartment of a vehicle comprises a sensing element for sensing the presence of an occupant within the closed compartment of the vehicle, a control responsive to the sensing element, and a release system. The control is operable to provide an output signal in response to a detection of an occupant by the sensing element. The control may be selectably locked to limit providing an unintentional output signal. The release system is operable to open the closed compartment in response to the output signal of the control. The control may be selectably locked in response to an input signal indicative of at least one of the vehicle ignition being on and the vehicle moving, in order to prevent the compartment from unexpectedly opening while the vehicle is moving.

Abstract: A system is provided for detecting the presence of a human in a compartment of a vehicle that comprises a pyroelectric sensor and a control coupled to the pyroelectric sensor. The pyroelectric sensor comprises a first sensing element and a second sensing element. The first sensing element is arranged in an opposed electrical connection with respect to the second sensing element whereby infrared radiation from a human moving within the compartment is selectively detected by one of the first sensing element and the second sensing element, thereby producing an output signal of the pyroelectric sensor. This output signal is received by the control, and the control generates a control signal indicative of detection of a human within the compartment.

Abstract: A system for sensing ambient conditions in a compartment, such as the trunk of an automobile, generates a control signal in response to the sensed conditions. This control signal actuates indicators to notify operators of the vehicle that there is a person trapped in the trunk. The control signal is also used to actuate a lamp inside the trunk to provide light for the trapped person. A trunk release is also actuated, by a control module, to free the trapped person. The trunk release of the automobile can be prevented from being actuated if the automobile is moving, which prevents the trunk lid from unexpectedly opening while the vehicle is in motion.

Abstract: A safety sensing and/or release assembly for a trunk or compartment of a vehicle is provided which is positionable within the trunk or compartment space of the vehicle so as to allow for opening of the trunk or compartment lid in response to an occupant detection or a manual actuation of the system from within the trunk or compartment. The safety assembly comprises a handle for activating a release mechanism of the lid in order to open the compartment, a release assist device, at least one illumination source, which is at least occasionally activated to provide illumination of the handle, and a control for activating the assist device or the illumination source in response to an occurrence of at least one activating event, such as when the deck lid is closed, motion is sensed by a sensor within the trunk/compartment, an object having a predetermined temperature is detected within the trunk/compartment, or the like.

Abstract: Pyroelectric detector systems may be used in vehicles for security applications, such as intrusion detection and anti-theft alarms. The pyroelectric detectors are small in size, highly reliable and consume very low power. They can be physically and electrically integrated with other vehicle components, including rear-view mirror assemblies in automobiles, without incurring additional installation costs. They can also be easily integrated into aircraft cockpits.
