Abstract:
The disclosed device is an additional, normally-closed relay positioned in line with the ignition switch and the functionality controlled by the OEM, normally-open relay. When the aftermarket system is in the disarmed state, the normally-closed relay is dormant in its closed position, thereby allowing the circuit to complete its intended loop. When the aftermarket security system is enabled, the normally-closed relay will open the current flow and prevent the current from reaching its target, thereby disrupting or disabling the operation of the vehicle function. If the normally-closed relay fails, it fails in its closed position, thereby not affecting the OEM system.
Abstract:
Disclosed herein is a sensing element with a sensing electrode, a reference electrode; and an electrolyte disposed between and in ionic communication with the sensing electrode and the reference electrode. A protective layer is disposed adjacent to the sensing electrode. A plurality of vias is disposed in the protective layer adjacent to the electrolyte and in fluid communication with the sensing electrode and a gas to be sensed. The vias have a diameter of about 50 micrometers to about 250 micrometers.
Abstract:
A low noise sinusoidal signal at a desired output frequency is synchronised using a first variable frequency oscillator (1) and providing a feedback control loop around the first oscillator (1) to generate a feedback control signal in successive frequ comparison steps using second and third frequency reference signals (44, 42). Each of the second and third frequency reference signals are derived from a first frequency reference signal, the second frequency reference signal (44) being compared with the output frequency of the first oscillator (1) to generate a frequency difference signal (43), and said frequency difference signal ( being compared in frequency with the third frequency reference signal (42) to generate said feedback control signal for the first oscillator (1), the frequency of the third frequency reference signal (42) being equal to the difference of the frequency of the se frequency reference signal (44) and the desired output frequency. The second and third frequency reference signals (44, 42) are generated by respective second and third frequency reference sources, the second frequency reference source comprising a second variable frequency oscillator (38) the frequency of which is maintained in a limited range around its optimum natural frequency to give optimum performance in producing a low noise output from the first oscillator (1).
Abstract:
A clip includes a body (10) and an opening (14) within the body and in which, in use, a part of a plant can engage. A slot (19), which is of doglegged configuration, extends between the opening (14) and an edge (17) of the body (10). The body (10) can be coupled to a means for providing support to the plant or part of the plant by a second opening (13) for which a slot (18) extends from an opposite edge (17) of the body (10).
Abstract:
A speaker system including in combination a speaker and surface mounting apparatus is disclosed. The speaker system has an adapter that secures the speaker system to the wall. A speaker box is secured to the adapter and has at least one speaker that is secured to at least one speaker portal wall of the speaker box, or speaker enclosure. A speaker portal wall is disposed in a plane that is oriented at an angle relative to the wall and is disposed outboard of the wall. A surface mounting adapter has a peripheral edge portion and a planar portion extending between the peripheral edge portion and the enclosure structure. Portions of at least four sides of the enclosure structure protrude from the planar portion of the wall. Other portions of at least four sides of the enclosure structure are recessed relative to the planar portion of the wall.
Abstract:
An embodiment of a scanning system is described including optical elements that direct an excitation beam at a probe array, detectors that receive reflected intensity data responsive to the excitation beam, where the reflected intensity data is responsive to a focusing distance between an optical element and the probe array, a transport frame that adjusts the focusing distance in a direction with respect to the probe array, an auto-focuser that determines a best plane of focus based upon characteristics of the reflected intensity data of at least two focusing distances where the detectors further receive pixel intensity values based upon detected emissions from a plurality of probe features disposed on the probe array at the best plane of focus, and an image generator that associates each of the pixel intensity values with at least one image pixel position of a probe array based upon one or more position correction values.
Abstract:
The invention relates to an improved propellor puller device for pulling a propellor hub from a marine engine. The propellor puller has a hub base member that has a central axis and a multiplicity of puller arms extending radially from the central axis. A threaded bolt threadably engages the hub base member so that rotation of the bolt is translated into axial displacement of the hub base member. Tension members composed of a series of chain links are slidably carried by a respective puller arm and attachable by a hook to a propellor blade. As tension in the tension members increases, the tension members will slide radially inwardly towards the central axis. The bolt carries a live center member that compressively engages the propellor shaft as the hub base member is axially displaced and the live center member allows rotation of the bolt while the live center member is locked rotationally with the propellor shaft; the live center member prevents the centering recess on the propellor shaft from becoming distorted and promotes a uniform distribution of the tension forces acting on the propellor hub to separate the propellor hub from the propellor shaft.
Abstract:
Wireless data services such as wireless email are becoming common, and in particular, “always-on” systems, where new email is automatically forwarded by the service provider to the wireless device. The problem is that there is no effective mechanism for implementing “always-on” systems when the user is moving around a network, or from one network to another. The invention addresses this problem by generating a session key at the service provider's system for a given data session, and returning this session key to the mobile device. Each time the mobile device communicates with the service provider, it enters this session key into a field that will simply pass through the communication network to the service provider. This allows the service provider to manage the data session, preparing proper accounting records and directing the deletion of stale data sessions on network resources.
