Patent number: 12237366Abstract: To provide a thin film capacitor having high adhesion with respect to a circuit substrate. A thin film capacitor includes: a metal foil having a roughened upper surface; a dielectric film covering the upper surface of the metal foil and having an opening through which the metal foil is partly exposed; a first electrode layer contacting the metal foil through the opening; and a second electrode layer contacting the dielectric film without contacting the metal foil.

Publication number: 20240269463Abstract: Nerve stimulation via a Low Frequency Alternating Current (LFAC) waveform can result in blocking of action potential conduction, while an increase in LFAC frequency and/or amplitude can translate into nerve activation. As LFAC for nerve blocking is frequency independent, the threshold LFAC activation can decrease with increasing frequency. Thus, frequency and amplitude settings can determine whether LFAC activates or blocks nerve fibers. LFAC can also be orderly, wherein smaller, non-fatiguing nerve fibers can be activated before larger nerve fibers. LFAC settings for activation can also be influenced by the configuration of a cuff assembly that positions an electrode along a nerve. The cuff can position a nerve in a cuff through hole, and a sliding closure of the cuff can be slide into a radial opening to substantially lock the nerve in the cuff assembly. An electrode material is positioned within a window of the cuff and is connected to an electrical lead.Type: ApplicationFiled: September 15, 2022Publication date: August 15, 2024Inventors: Kenichi Yoshida, Michael Ryne Horn, Awadh Al Hawwash, Nathaniel Lazorchak, Christian Phillip Vetter, Onna Marie Doering

Publication number: 20230371175Abstract: To prevent interfacial peeling due to the stress of an insulating layer in a capacitor-inductor integrated electronic component having three or more conductor layers. An electronic component includes: a conductor layer M1 including a conductor pattern constituting an inductor; a conductor pattern overlapping a part of the conductor pattern through a dielectric film; an insulating layer covering the conductor layer M1 and conductor pattern; a conductor layer M2 provided on the insulating layer and including a conductor pattern constituting the inductor; and an insulating layer covering the conductor layer M2.
