Abstract: A device includes a touch-mode biometric sensor having a first side facing toward a user and a second side opposite to the first side, and a display arranged under the touch-mode biometric sensor and adjacent to the second side and configured to display an image in response to a sensing result, associated with a biometric feature of the user, of the touch-mode biometric sensor.

Abstract: A solar cell includes a photovoltaic substrate having a first surface and a second surface and a plurality of bus bar electrode net structures. The bus bar electrode net structures are separately disposed on the first surface, each bus bar electrode net structure includes a bus bar electrode, a plurality of finger electrodes, at least one connecting line electrode and at least one vertical finger electrode. The bus bar electrode is disposed on the first surface. The finger electrodes are separately disposed at two sides of the bus bar electrode. The connecting line electrode is disposed on the first surface. Each connecting line electrode connects with ends of at least two finger electrodes. The vertical finger electrode is disposed on the first surface, and is parallel to the bus bar electrode and disposed between the two ends of the finger electrode to connect with at least two adjacent finger electrodes.

Abstract: A method for estimating maintenance dates includes steps of obtaining one or more differences between detected values and maintenance values of parameters, and determining whether the differences are beyond predefined values. The method further includes a step of implementing or recommending an initiation of maintenance if any of the differences are beyond their respective predefined values. The method also includes a step of estimating the maintenance date according to the differences and variation values representing changes of the parameter per time unit for the tool, if none of the differences are beyond their respective predefined values. An apparatus for estimating maintenance date in this fashion is also presented. The apparatus includes a controller, a database, and a connection unit.

Abstract: The invention discloses the design of a low profile transformer, which is smaller in size and lighter in weight. The low profile transformer will meet the isolation safety standard and is manufactured with low cost. Furthermore, a variety of cores could be applied to the low profile transformer for a wide range of electrical current loading.

Abstract: A mobile phone holder includes a first plate and a second plate, each plate being "L" shaped and a slot is further provided respectively within the first plate and the second plate, a retaining member movably secured within the slots, a sound transmitting member provided on the second plate. The plates are combined such that vertical faces oppose each other with horizontal faces overlapping with aligned slots. The sound transmitting member has a sound resistent material securely attached on the second plate, a hollow connector securely connecting with the hole of the second plate, a conductor having a first end securely connected with the connector, and a second end securely connected with an ear plug. A mobile phone is able to be received with the holder as described previously, therefore, a user then easily receives a conversation through the ear plug and the conductor.

Abstract: A coaxial cable connector including a screw threaded tube, a male clamping tube and a female clamping tube. The male clamping tube has a central hole, a rear projection pipe and a clamping portion, whereby an insulating portion of a concentric coaxial cable fits into the projection pipe with an outer cover and separate grounding wire sheath of the concentric coaxial cable fitted between the projecting pipe and clamping portion. The inner wall of the female clamping tube is formed with rearwardly tapering inclined portion whereby when the female clamping tube is fitted to the male clamp portion, the tapering portion presses the clamping section of the male clamping tube making the saw tooth portion of the inner wall of the clamping portion securely bite into the concentric coaxial cable. An annular projecting shoulder formed on an outer wall of the clamping portion of the male clamping tube engages an annular groove formed on inner wall of the female clamping tube to join the male and female clamping tubes.
