Safety device for prevention of electrical shocks
InactiveUS7400476B1Avoid contactEmergency protective arrangements for automatic disconnectionEmergency protective arrangements for limiting excess voltage/currentElectrical ProblemPower utility
A safety device can provide electrical shock protection for an electrical appliance. Voltage sensors can monitor voltage levels among a power conductor, a neutral conductor, and a ground conductor. When sensed voltages indicate that these conductors are properly wired to an electrical power utility, inline switches can close to allow power to pass through the safety device to the appliance. When one or more of the sensed voltages indicates that the power level is too low to operate the appliance, one or more switches of the safety device can open to block power from passing through to the appliance. When one or more of the sensed voltages indicates that an electrical problem posing a shock hazard exists in the electrical appliance, one or more switches of the safety device can open to interrupt power from transmitting to the appliance.

InactiveUS20050052600A1Long-term reliabilitySolve the real problemNon-linear opticsElectrical ProblemLiquid-crystal display
In a reflective liquid crystal display device according to the invention, while maintaining alignment characteristics by an obliquely evaporated alignment film, an electrical problem due to the film structure can be solved, and ions or the like can be prevented from passing through an alignment film, thereby long-term drive reliability can be achieved. Further, misalignment and nonuniform alignment due to the structure of an inter-pixel groove can be prevented so as to achieve superior image quality. In a side of each of a pixel electrode substrate and a transparent electrode substrate closer to a vertically aligned liquid crystal, an obliquely evaporated alignment film is formed on a vertically evaporated film. As the vertically evaporated film is formed as a base film, while maintaining the alignment characteristics of the obliquely evaporated alignment film, an electrical problem due to the film structure can be solved, and ions or the like can be prevented from passing through the obliquely evaporated alignment film so as to achieve long-term reliability. Further, an obliquely evaporated alignment film is formed on a region of the inter-pixel groove through evaporation from an oblique direction with respect to the substrate surface of the pixel electrode substrate, so misalignment and nonuniform alignment due to the structure of the inter-pixel groove can be prevented.

Many embodiments involve rechargeable battery assemblies that are forklift-battery-sized but that comprise multiple removable battery modules. The removable battery modules are individually rechargeable and are interchangeable with each other. A housing contains six battery modules installed vertically on the front side of the assembly, with their electrical and data connections occurring within the housing on the rear side. Assemblies will be two sided so that the system has two racks with six modules per rack. The handles of each module are collapsible and on the top edges of the overall assembly so that they are readily accessible during removal. Each battery module has an integrated battery supervisor system (BSS). A Battery Operating System Supervisor (BOSS) module processor serves as a battery management system for the all the battery modules. The BOSS module grants permissions to battery modules to enable them to connect and disconnect from busbars at the appropriate times to prevent electrical issues.

The system and method for determining the operational condition of an electric fuel pump (16). The test apparatus (22) is configured to perform first, second and third tests. During the first test, a low voltage, low current signal is applied to produce an inductive reflectance from the pump armature winding. During the second test, continuity is assessed in the coil winding circuit. During the third test, a higher power, short duration pulse is applied to create rotational movement of the pump armature for the purpose of detecting mechanical and / or electrical issues not otherwise discerned from the prior tests. An optional fourth test may be conducted in which the pump (16) is run for a short period of time at standard operating power to generate a current waveform. Collected test data is compared to stored reference data sets using a processor contained within the test apparatus (22). If collected test data corresponds within an acceptable threshold range to the reference data, a PASS signal is generated.
