Abstract: Techniques are described for low-noise self-capacitor sensing in a capacitive touch panel array integrated with a display panel. Each channel of the array has a self-capacitance (Ci) that changes responsive to presence or absence of a local touch event local. Each channel is read by an analog front-end (AFE) by using a locally noise-suppressed discharge current for a discrete discharge time to discharge Ci to obtain a discharge voltage level that differs with presence or absence of the local touch event, and outputting a voltage output for the channel based on the discharge voltage level by passively mixing at least the discharge voltage level to produce a pair of up-converted channel signals, sampling the pair of up-converted channel signals to obtain a differential voltage sample, and amplifying the differential voltage sample to generate the Vout as indicating absence or presence of the touch event local to the channel.

Abstract: Techniques are described for using a multi-branch AC-mode bridge approach with global current rotation for self-capacitor sensing in a capacitive touch panel, such as integrated into a display of a touchscreen electronic device. K channels are coupled with K branches of a multi-branch AC-mode bridge to form K?1 pairs of channels for concurrent differential readout. K nominally identical sinusoidal input currents are generated based on an error signal, which is generated based on comparing a sinusoidal driver signal with feedback from one or more of the K branches. A unit current rotator rotates the K sinusoidal input currents to each of the branches, so that each branch current is formed by a rotating contribution from each of the sinusoidal input currents. Driving each branch with its branch current manifests a respective branch voltage, and differences between the branch voltages can be used to differentially sense pairs of channels.

Abstract: Techniques are described for discrete-time self-capacitor sensing in a touch panel. The self-capacitor manifests a detectably different capacitance based on presence or absence of a local touch event on the touch panel. In a first time phase, embodiments charge a self-capacitor and initialize a ramp bias generator. In a second time phase, embodiments discharge the self-capacitor with a ramp-controlled current source that is biased by the ramp bias generator to produce a discharge current that transitions from high at the beginning of the second time phase to low at the end of the second time phase. By the end of the second phase, the remaining charge in the self-capacitor depends on presence or absence of a local touch event. Some embodiments convert the remaining charge to an amplified sense output for readout.

Abstract: The invention is a polyoxymethylene film and a preparation method. The polyoxymethylene film comprises: 96 to 98 parts by weight of polyoxymethylene resin, 0.5 to 2 parts by weight of nucleating agent, 0.5 to 1 parts by weight of antioxidant, and 0.5 to 1 parts by weight of formaldehyde absorbent. In view of the high crystallinity and fast crystallization rate of polyoxymethylene, blown film process is used to directly blowing the molten mass extruded through a die of a screw extruder to form a blown film bubble. It is easy to form thin neck and easy to break when stretching, so the method is beneficial to form polyoxymethylene film, and has high processing efficiency, and is suitable for industrialization. Copolymerization unit —CH2—CH2—O— is introduced into the molecular chain of polyoxymethylene and its ratio is increased, thereby effectively reducing the crystallization rate of the materials and making it easier to form a film.

Abstract: A blood vessel metal stent coating of amidoglucosan polysaccharide loaded with antibody comprises carrier material composed of chitosan and inartificial degradable acidic amidoglucosan polysaccharide and the effective dose of CD133 antibody loaded in the carrier material. The blood vessel metal stent coating is manufactured with self-assemble method to fix the CD133 antibody in the carrier material of the coating. The coating has good biocompatibility, water retention property, flexibility, flush resistance and bio-stability, and can specifically capture the vascular endothelial progenitor cells in human peripheral blood, and differentiate into vascular endothelial cells. The process would accelerate endothelialization to repair injured vessel caused and prevent restenosis and thrombosis efficiently.
