A method is disclosed for forming a chamber in an electronic device, including the steps of preparing an outer surface on a solidified core material, the solidified core material in a depression formed in a substrate. The method further includes establishing a layer on the prepared outer surface of the solidified core material and a portion of the substrate surrounding the depression. The established layer and the substrate define a chamber.

A micro-mirror device includes a micro-mirror and a flexure spring supporting the micro-mirror. The flexure spring is configured to store potential energy during movement of the micro-mirror that is released as kinetic energy to drive movement of the micro-mirror when the micro-mirror is re-oriented.

Representative embodiments provide for a fuel cartridge including a film strip supporting a fuel compound. An electric heater of the fuel cartridge is configured to heat a portion of the film strip, wherein the fuel compound is configured to liberate hydrogen gas from the heated usable portion of the film strip. The fuel cartridge is configured to provide the hydrogen gas to a fuel cell by way of a fluid coupling there between. The fuel cartridge is configured to support the film strip and the electric heater in a substantially self contained arrangement. A method includes supporting a film strip including a fuel compound within a fuel cartridge, heating a portion of the film strip within the fuel cartridge, and providing hydrogen gas liberated by the heating to a fuel cell.

A book holder for use with automobile steering wheel is not only fastened to the rim of an automobile or truck steering wheels so as to hold printed matter and various electronic devices, but also is foldable to smaller size for storage. The book holder can also be used as a desk to read and write on it and can be installed or removed from the steering wheel within seconds. This book holder includes two built-in elastic bands to prevent unexpected book turning pages and two elastic loops for holding the pens.

A method and apparatus providing a micro-mirror device configured to increase actuation speed thereof. The micro-mirror device includes a substrate, a mirror, a spring member and at least one adjacent micro-mirror device. The mirror is suspended over the substrate and configured to deflect in response to an actuation force. The spring member is suspended between the substrate and the mirror. Further, the spring member is configured to store energy upon being deflected by the mirror and is configured to release the stored energy to force the mirror to another position. The at least one adjacent micro-mirror device is positioned over the substrate adjacent the mirror and is configured to suspend the spring member.

A method and apparatus providing a micro-mirror device configured to increase a switching frequency thereof. The micro-mirror device includes a substrate with at least one address electrode positioned over the substrate to provide an electrostatic force and includes at least one support member positioned over the substrate and extending upward above the substrate. The micro-mirror device also includes a mirror and a spring member. The mirror is disposed over the at least one address electrode and coupled to the at least one support member. The mirror is configured to deflect toward the substrate in response to the at least one address electrode applying the electrostatic force to the mirror. The spring member is spaced apart between the substrate and the mirror and coupled to the at least one support member. The spring member is operable to deflect separately from the mirror and toward the substrate.
