Abstract: A protection device comprises a substrate, a fusible element and a heating element. The substrate comprises a first electrode and a second electrode on its surface. The fusible element is disposed on the substrate and connects to the first electrode and the second electrode at two ends. The fusible element comprises a first metal layer and a second metal layer disposed on the first metal layer. The second metal layer has a lower melting point than that of the first metal layer. The heating element is disposed on the substrate. In the event of over-voltage or over-temperature, the heating element heats up to melt and blow the fusible element. The second metal layer is 40-95% of the fusible element in thickness.

Abstract: A protection device comprises a substrate, a fusible element, a flux and an insulating cover. The fusible element is disposed on the substrate and connects to a power line of an apparatus to be protected. The flux is disposed on the fusible element. The insulating cover is secured on the substrate to form a room for receiving the fusible element. The insulating cover has a bottom surface facing the substrate, and a plurality of protrusions are formed and distributed on the bottom surface to hold the flux in place.

Abstract: A secondary battery connecting to an external circuit through a first output terminal and a second output terminal. The secondary battery comprises an accumulator, a plurality of protective circuits and a switch element. Each of the protective circuits comprises two fuses connected in series to form a series circuit, a heater for blowing the fuses and a rectifier element in parallel connection to the heater. The series circuits of the two fuses are connected to each other in parallel. One end of the rectifier and the heater is connected to a junction between the two fuses, and another end of u) the rectifier and the heater connect to the switch element. One of the two fuses of each of the protective circuits connects to the first output terminal, and the switch element connects to the second output terminal.

Abstract: A protection device comprises a first planar substrate, a second planar substrate, a heater and a fusible element. The first planar substrate comprises a first surface, and the second planar substrate comprises a second surface facing the first surface. The heater comprises a first heating element and a second heating element in parallel connection, and the first heating element is disposed on the first surface. The fusible element is disposed on the first surface and adjacent to the first and second heating elements, thereby the fusible element is melted by absorbing the heat generated by the first heating element and/or second heating element. The second heating element has a resistance at least twice that of the first heating element.

Abstract: The present invention provides an image sensing module including an image sensing device and a calculation device. The image sensing device includes a plurality of pixels for acquiring an operation image containing an object image. The calculation device stores a look-up table regarding a temperature related parameter and a position deviation of the object image at each pixel associated with the temperature related parameter, and selects a deformation error from the look-up table according to the temperature related parameter corresponding to the operation image so as to correct a current position of the object image in the operation image.
