Systems and methods for providing registration at a remote site that may include, for example, a monitoring module that may communicate with a remote site. A registration protocol may be used by the monitoring module and the remote site in generating the messages communicated during the registration process. The monitoring module may gather and generate various identification information to be included in the registration protocol messages. The registration information provided by the monitoring module may be stored at the remote site in a database server having a database. A confirmation message may be communicated from the remote site to the monitoring module that may either acknowledge successful registration or report that an error occurred during the registration process.

The present invention is directed to a cushioning device. The present cushioning device has many attributes that are common with many cushions. Some of these common attributes are at least one bladder having a top surface, a bottom surface and at least one side surface positioned between the top and the bottom surfaces. Another common attribute is a bladder cavity being defined by the top surface, the bottom surface and the at least one side surface. The present invention differs from other bladders in that there is a first conductive material and a second conductive material are positioned within the bladder cavity, positioned away from the bottom surface of the bladder, and capable of acting like a switch for a reactive device. The reactive device is electrically interconnected with the first and second conductive materials. When the first and second conductive materials contact each other the reactive device is capable of responding by sounding an alarm and/or re-inflating the bladder cavity with a fluid.

The system integrates environmental parameter sensing measurement with wireless transmission, network communication and other technologies and effectively solves the problems of automatic collection and transmission of ecological environment information in the orchard. Atmosphere and soil information sensor nodes are evenly distributed in a region to be monitored of the orchard,, monitor atmosphere and soil parameters of the position where each node is positioned respectively and are connected to form an information transmission network through respective wireless communication module; and a blind spot of a wireless routine signal is added with a mobile node for maintaining the communication and reliability of a communication route and finally transmitting data to the converged node.

A tamper sensing circuit is provided for an electrical device wherein an enclosure may be opened to access data by a user that does not possess the ability to achieve normal access by satisfying data security measures such as use of a password. A screw used to secure enclosure halves together is connected by a conductive coating at the enclosure member surface into which the screw is threaded to connect a tamper sensing circuit to the device ground potential. A tamper sensing circuit output node is maintained at the circuit ground potential as long as the screw is in electrical contact with the enclosure conductive coating. When the screw is disengaged from the enclosure member threaded opening, the output node is no longer grounded and rises to a supplied electrical potential indicating tampering and enabling appropriate corrective action. The conductive coating on the enclosure member which connects the screw to circuit ground may be applied or may already be present to suppress electromagnetic interference.

The Med-ic™ Electronic Compliance Monitor (ECM) addresses the problem of patient non-compliance with prescribed medication. The Med-ic™ ECM provides precise information about the patient's use of blister-packaged medication in clinical research and general pharmacy settings. Using an on-board central processing unit (CPU), the Med-ic™ ECM records the time each tablet or capsule is expelled from the blister package, keeping a record for later analysis. At the time of refilling or follow-up visit, the information is downloaded to the research assistant's, physician's or pharmacist's computer where it can be displayed graphically. The data can be stored for later analysis. Production of a Med-ic™ ECM Tag involves numerous steps. These steps incorporate certain methods and technologies to accomplish their objective, the steps being detailed in the specification.

A software driven, solid state controlled, electro-mechanically operated system to monitor volatile liquid fuel or other hazardous liquids and provide emergency shut-off if the delivery system is ruptured. A computer receives input from transducers monitoring the flow rate of the liquid through the line and a pressure sensor insures the system is prepared to function. The monitoring apparatus presets a condition based on current environmental conditions. Measuring the flow rate provides input to software that validates all other entries. Delivery quantities allowing point of delivery control to vary the delivery quantity to individual locations. The software options are: Preset conditions; Owner/operator input via external computer for loading delivery and trip instructions; Instructional output on LCD screen to driver on customer information and scheduling; Data download to owner/operator on billing information, driver daily activities and volume of propane remaining in vehicle.

In a liquid crystal display device having a front window, light from a backlight is prevented from leaking through chamfered edges of the front window. An upper polarizing plate is formed on an opposing substrate and a light shielding material is formed abutting on an outer edge of the upper polarizing plate. Edges of the upper polarizing plate are located inward of edges of the front window. The upper polarizing plate and the front window are bonded with a boding material including an ultraviolet curable resin. The ultraviolet curable resin also lies over the light shielding material. Chamfers are formed in the front window and the ultraviolet curable resin does not adhere to the chamfers of the front window. By this structure, light from the backlight is prevented from entering the internal part of the front window through the chamfers of the front window and light leakage is prevented.

A sensor system (1; 20; 30; 40) is proposed for detecting forces which, particularly in the case of a motor vehicle, lead to a deformation of components, e.g. body parts (10) as the result of an accident. The sensor system (1; 20; 30; 40) has a number of contact elements (2, 3, 4; 21, 22, 23; 31, 32, 33) which are arranged on the component (10) staggered one behind the other in a possible deformation direction (11), compressible insulation layers (5, 6, 7; 24, 25; 35, 36) being disposed between the contact elements (2, 3, 4; 21, 22, 23; 31, 32, 33). The contact elements (2, 3, 4; 21, 22, 23; 31, 32, 33) are electroconductively connected to an electronic evaluation circuit by which a contacting and/or de-contacting of adjacent contact elements (2, 3, 4; 21, 22, 23; 31, 32, 33), caused by a deformation, is able to be detected and converted into control and or regulating signals.

The invention concerns a method for anticipating and/or delaying and/or preventing the risk of spontaneous combustion and/or explosion of an explosive atmosphere preserved in a confined or semi-confined medium, which consists in measuring the temperature of the mixing from the moment said mixture has been created and determining the critical moment of spontaneous combustion and/or explosion of said atmosphere by determining the unexpired inducting period, on the basis of the time which has elapsed between the creation of said atmosphere and the critical moment beyond which there is a risk of spontaneous combustion and/or explosion of said atmosphere.
