Abstract: A wireless tandem alarm having a first alarm configured for physical connection to an industrial machine having an electronic machine controller, and a second alarm configured for detachable connection to the first alarm or to the industrial machine. Each alarm has a housing, a piezoelectric transducer within the housing, a processor configured to drive the piezoelectric transducer in response to a control signal, and a wireless transceiver configured for relatively short-range, low-power communications. In the first alarm, the processor drives the piezoelectric transducer in response to a signal from the machine controller and, also responsive to the machine controller signal, transmits a control signal via the wireless transceiver. In the second alarm, the wireless transceiver receives the control signal from the first alarm and supplies it to the processor, which is configured drive the piezoelectric transducer in response.

Abstract: A panel-mountable audible and visual warning device comprising a main housing and a cap thereon, the device configured to have the main housing fit into a hole in the face of a mounting panel and to have the front wall and side wall of the cap external to the panel when the device is operably mounted therein, with the cap containing a piezoelectric transducer and at least one LED as a modular subassembly which is attached to the main housing. The cap and transducer together define an audio-frequency resonant cavity, and the cap has the LED(s) mounted therein in a position in front of the panel face in use and behind and radially outward of the transducer so as to emit light directly forward past the transducer.

Abstract: A panel-mountable audible and visual warning device having an internal volume control shutter within a resonant cavity defined by the device housing and a sound generating element within the housing. Another embodiment has a cap on a main housing which fits into a hole in a mounting panel, with the cap external to the panel, the cap having multiple LEDs mounted therein in front of the panel face and behind and radially outward of a piezoelectric transducer so as to emit light directly forward past the transducer. Another cap embodiment has a piezoelectric transducer, LEDs, and a pushbutton switch mechanism including a movable surface portion of the cap's front wall and an internal set of switch contacts operably connected thereto. A control circuit can partially disable the alarm signaling function, such as by muting the transducer but continuing to energize the LEDs in response to actuation of the switch.

Abstract: A system for using a separate fixed or massive object to prevent theft of a motorcycle, the system comprising a frame element including a hollow enclosure having a wall with an orifice therethrough; a reel rotatably mounted in the enclosure; a flexible electrically conductive sheathed cable with a proximal end wound onto the reel and a distal end with a male connector; a control mechanism having an alarm mechanism, a female connector, circuitry to connect the female connector to the proximal end of the cable, to detect presence or absence of continuity between the proximal end and distal end of the cable, and to cause the alarm mechanism to be activated when continuity between the proximal end and distal end of the cable is broken; a locking mechanism having a locked configuration wherein the male connector is prevented from being withdrawn from the female connector, and an unlocked configuration wherein the male connector is allowed to be withdrawn from the female connector; and a power source structured to

Abstract: The invention is an modified audible signal, such as a piezoelectric noise-making and audible signaling device, which further includes a hydrophobic covering material, such as polytetrafluoroethylene (PTFE). The hydrophobic covering material is known to be water resistant, but does not effect the sound of the audible signaling device, thereby delaying or preventing the failure of the audible signaling device from water corrosion.

Abstract: The disclosed embodiments comprise a Rate Engine and system and method for the use thereof, which may execute on a computer or other processor and which provides cost analysis with a finer granularity than monthly or billed costs. The Rate Engine receives inputs such as utility data and rate data, and generates cost data on a per logging interval basis. A logging interval is the finest sampling frequency available, which varies depending on the application, such as from microseconds to minutes or hours. The resulting cost breakdown allows the user understand and analyze their energy costs in the same manner that they analyze other costs of business such as labor and goods.

Abstract: The invention is an improved noise-making device using a piezoelectric transducer where electrical circuit components are mounted directly on the transducer itself rather than being mounted on a separate printed circuit board. Directly mounting the components eliminates the need for a separate circuit board and eliminates a third terminal from a three-terminal device. As a result, the entire device requires less material and labor, and is therefore less expensive. The elimination of the circuit board also can contribute to a reduction in size of the noise-making device.

Abstract: The convoluted fluorescent lamp component of a compact lamp unit is mechanically and electrically coupled to a base module by a plate-like mounting member which is secured to the module in suspended fashion and has socket means which permit the lamp component and associated energizing-circuit components to be plugged into and removed from the module. The mounting member is structured and oriented to also provide a peripheral air passageway which, in conjunction with vent openings in the module and in a protective cover which is secured to the module, allows air to flow freely through the operating unit and convection-cool the fluorescent lamp. The lamp unit can accordingly be operated at high power loadings without overheating and can also be easily relamped and provided with new circuit components (such as a ballast and/or a starter) to prolong its useful life.
