A method of making a touch-sensitive data entry screen of the kind arranged to provide haptic response to a user via at least one electromechanical exciter coupled to the screen, comprising analyzing the mechanical and electromechanical coupled system represented by the data entry screen and the at least one exciter, and selecting values of parameters of the coupled system to provide a required displacement and acceleration of the screen at low frequency in response to human touch.

One embodiment is directed to a tray for use in a subrack of a rack. The tray comprises a printed circuit board configured so that a plurality of connections can be made at a plurality of positions on the printed circuit board, each of the plurality of connections involving at least one connector positioned on a patch side of the plurality of positions and the least one connector having a device associated therewith in which information is stored. The tray is configured so that either side of the positions can be used as the patch side. The tray is configured so that the devices associated with the connectors involved in making the connections at the patch side can be read via the tray. The devices associated with the connections can be implemented, for example, using RFID tags or connection point identifier (CPID) storage devices (such as EEPROMs).

One or more apparatuses and methods for enabling easy diagnosis, repair, and maintenance of a commercial display screen are disclosed. In one embodiment of the invention, this apparatus includes a removable commercial display kit box, a corresponding base plate interface unit attached to a rear panel of the commercial display screen, and a guiding mechanism for docking the removable commercial display kit box and the corresponding base plate interface unit. Furthermore, in one embodiment of the invention, the removable display kit box contains an analog-to-digital converter board, a power board, automatic-switching dual data ports, maintenance check visual indicators, and a removable fuse inlet. In case of a commercial display screen malfunction, the removable display kit box allows a quick inspection and a modular repair or replacement of a malfunctioning part, without requiring the entire commercial display screen to be dismounted from a wall or another attached structure.

A method of manufacturing an overheat or fire alarm detection system, comprises the steps of micromachining a pressure sensor and securing a sensor tube in fluid communication with the pressure sensor. The sensor tube may comprise a hollow tube containing a material that evolves gas upon heating. The micromachining step may comprise doping at least a portion of a first layer, forming a cavity at least partially within the doped portion and forming a deformable diaphragm over the cavity.

The present invention discloses a folding vibration microgenerator and a method of manufacturing the same. The microgenerator comprises a foldable sandwiched substrate, wherein the foldable substrate comprising two flexible insulating substrates and an induction electrode located between the two flexible insulating substrates, in which the induction electrode is constructed by two complementary comb-shaped electrodes. The foldable substrate has upper and lower surfaces, on which the first friction structure units and the second friction structure units are respectively periodically distributed, and the first friction structure units corresponds to the odd-numbered comb teeth of the induction electrode and the second friction structure units corresponds to the even-numbered comb teeth of the induction electrode. The foldable substrate is folding at gaps between two adjacent comb teeth of the induction electrode as a serrate shape, thereby forming a folding vibration microgenerator. The microgenerator is easy to be produced and largely increases output power per unit area. Due to inflexibility of the folding structure itself, the energy conversion efficiency of the microgenerator is effectively increased while output power being maintained.

A method for laying multiple conductors in a container may be provided. The method may comprise receiving the multiple conductors at a monitoring station; receiving the multiple conductors at a drive; and receiving the multiple conductors at the container.

Two or more strings are connected in parallel. The strings each include two or more cells and a fuse. The two or more cells are connected in series. The fuse is connected in series to the two or more cells. Combustion of the cells do not occur when heat generated per unit time by the cells is less than or equal to an upper limit. The number of series-connected cells is determined to be less than or equal to a threshold value, within which the electric power converted into heat by a short-circuited cell in the event of a failure reaches the upper limit. The fusing current matches with a charging current that flows to a fault string when the electric power converted into heat by a short-circuited cell in the event of a failure reaches the upper limit.

In some embodiments, processes for testing for structural flaws in sapphire parts such as display cover plates used in the manufacturing of electronic devices are disclosed. A process may include transmitting a destructive acoustic signal onto a sapphire part, and determining whether the sapphire part failed in response to the destructive signal. The destructive acoustic signal may include a Rayleigh acoustic wave, wherein the destructive acoustic signal breaks the sapphire part if the sapphire part has a surface flaw larger than a specified size. In this manner, only sapphire parts that can withstand the destructive acoustic signal are used in manufacturing of the electronic device.

A solar charging umbrella uses solar power to charge electronic devices wirelessly, such as by a wireless or inductive charging port. The umbrella is self-sustained, capable of charging electronic devices in locations away from electrical outlets. The umbrella has a rechargeable battery that is recharged by sunlight. When charged, the umbrella's battery can charge devices when sunlight is not available. The umbrella supports simultaneous charging of higher power devices such as tablet computers.

Control device 80 of component mounter 11 performs control such that after a component supplied by reel unit 56 is picked up by nozzle 40 of mounting head 24 and before the component is mounted on board 12, the component is temporarily placed at a specified position of temporary placement surface 71. Also, control device 80, after performing control such that the component is temporarily placed at the specified position, determines whether the component has actually been temporarily placed at the specified position based on the pressure state at a hole provided at the specified position of temporary placement surface 71 to which negative pressure is being supplied, and performs processing according to the determination result. Because the determination of whether the component has actually been temporarily placed is based on the pressure state of the hole provided in temporary placement surface 71, the determination is performed rapidly compared to a case in which the presence of the component is checked by analyzing an image of temporary placement surface 71 captured from above.
