Abstract: A differential pressure sensor, wherein a gas pipeline (12) is formed in an IC carrier plate (10) and two air holes (13) in communication with the gas pipeline (12) are arranged on the top surface of the IC carrier plate (10). A pressure sensing chip (30) is integrated with one of the air holes (13) on the IC carrier plate (10), and an upper cover (40) is adhered and combined on the top surface of the IC carrier plate (10); two cavities (411) are arranged on the upper cover (40) and correspond to the positions of the two air holes (13), and two air pipes (42) respectively connected to the cavities (411) are arranged on the upper cover (40).

Abstract: The present invention discloses a Micro-Electro-Mechanical System (MEMS) pressure sensor device and a manufacturing method thereof. The MEMS pressure sensor device includes: a substrate having at least one recess formed on an upper surface thereof, the recess defining a boss; a membrane, which is bonded to at least a part of the upper surface and at least a part of the boss, so that the at least one recess forms a cavity; at least one sensing unit, which is coupled to the membrane, for sensing deflection of the membrane; and an opening, which is formed on a lower surface of the substrate, and connects to the cavity.

Abstract: A portable cardiopulmonary resuscitator for implementing CPR to rescue a user includes a pressing mechanism and a respiration aid. The pressing mechanism includes a pressing element and a pumping element. The pressing element is pressed to massage a heart of the user and the pumping element is operated to produce and discharge air. The respiration aid includes a tube and a mask, an end of the tube is extended from the pumping element and the other end of the tube is provided with the mask which is covered on a face of the user. By the aforementioned structures, a rescuer can use the present invention to perform the CPR to a patient, with infection of germs by being in contact with saliva being avoided, which is indeed provided with practical progressiveness.

Abstract: A method of using matrix to adjust hue and color saturation includes the following steps: transform a YUV format signal into a RGB format signal with a first matrix; the RGB format signal is multiplied by a second matrix to obtain a RGB format signal whose hue and/or color saturation can be adjusted.

Abstract: The present invention relates an access method for flash memory in an embedded system, including the following steps: divide the flash memory into a main program zone and a storage zone; provide an access circuit having a command register for receiving commands and a microcontroller status buffer; the access circuit detects if the microcontroller executes the command to access the storage zone and, if not, continues to detect; when the microcontroller executes the command to access the storage zone, the access circuit stores the command in the command register for receiving commands, stores the status of the microcontroller in the microcontroller status buffer, and executes the read/write command for the storage zone; the access circuit stores the results of the read/write commands in the command register for receiving commands; and the access circuit retrieves the status of the microcontroller from the microcontroller status buffer to return the microcontroller to its original status to continuously execute

Abstract: A suspensible flat Christmas tree comprises at least one triangular frame, a hanger mounted on a top of the Christmas tree, a stand for supporting the at least one frame in an upright position, and at least one branch wrapped and interlaced on the frame and defining a plurality of hanging cavities for hanging gifts therein.

Abstract: This invention relates to crosslinked polymer foam compositions of an ethylene vinyl acetate copolymer, an acid copolymer or ionomer, and a crosslinking agent. Such compositions exhibit enhanced melt strength, as well as lower density and compression set. They are especially useful as midsoles or insoles for footwear.
