Patent number: 11856898Abstract: An automated mushroom harvesting system for mounting to a vertical mushroom rack comprises a robot having a frame mounted to a vertical carriage assembly. A SCARA arm is slidably mounted to the vertical carriage assembly by a vertical stage, operable to move the SCARA arm along a vertical mast. The SCARA arm moves the end effector in a horizontal plane for harvesting mushrooms, above the surface of the mushroom bed and into and out of the confines of the mushroom rack, and the vertical stage moves the SCARA arm in a vertical direction so as to access the mushrooms in a bed and to access mushroom beds on different levels of the vertical mushroom rack. An end effector having a helically reinforced neck and a graduated elasticity modulus, with a lower elasticity modulus in the neck and a higher elasticity in the cup, is also provided.Type: GrantFiled: August 3, 2021Date of Patent: January 2, 2024Inventors: Michael Howard Boudreau, Kyran Ashley Lawrence Findlater, James Boyd Gibson, Clark Allan Richardson

Publication number: 20230421968Abstract: Provided is an electrostatic clutch. The electrostatic clutch includes: multiple arrays of HIN electrodes, a respective pass-through channel being formed between any two arrays of the multiple arrays of HIN electrodes; and multiple arrays of biased electrodes, each array of the multiple arrays of biased electrodes moving back and forth in the respective pass-through channel such that electrostatic force is generated between the multiple arrays of biased electrodes and the multiple arrays of HIN electrodes. Such configuration allows microphone performance over a wide range of atmospheric pressures which is likely expected by applications. This is achieved electrostatically in a purely passive way having advantages over other designs which require complex electronics and active control. Physically decoupling the membrane and sense structure simplifies design of the sense structure as only small AC perturbations of the rotor is considered with no DC changes in rotor position.Type: ApplicationFiled: June 28, 2022Publication date: December 28, 2023Inventors: Anup Patel, Euan James Boyd, Yannick Pierre Kervran

Publication number: 20230331543Abstract: Provided is a MEMS device and an electro-acoustic transducer. The MEMS device includes: a substrate having a cavity passing through the substrate; a diaphragm connected to the substrate and covers the cavity. The diaphragm includes oppositely arranged first and second membranes. The first membrane is on one side of the second membrane facing away from the cavity and includes a first protrusion extending away from the second membrane, the first protrusion has a first groove opening towards the second membrane. The second membrane includes a second protrusion extending away from the first membrane and opposite to the first protrusion, the second protrusion has a second groove opening towards the first membrane. By providing first and second protrusions on first and second diaphragms to form a corrugated diaphragm, the internal stress and stiffness of the diaphragm decreases, which effectively increases the mechanical sensitivity of the MEMS device.Type: ApplicationFiled: April 18, 2022Publication date: October 19, 2023Inventors: Yannick Pierre Kervran, Euan James Boyd, Colin Robert Jenkins, Colin Wei Hong Chung, Scott Lyall Cargill

Patent number: 11750973Abstract: A microelectromechanical system includes an enclosure defining a cavity and an opening communicating with the cavity; a membrane mounted at the opening; a cantilever located within the cavity, the at least one cantilever comprising a first end, a second end and a fulcrum located between the first end and the second end; a plunger positioned between the membrane and the cantilever and configured to transfer displacement of the membrane to the first end of the cantilever; and a sensing member connected to the second end of the cantilever.

Patent number: 11677337Abstract: A comb drive for MEMS device includes a stator and a rotor displaceable relative to the stator in a first direction. The stator includes stator comb fingers and the rotor includes rotor comb fingers. The stator comb fingers are coupled to two high impedance nodes to form high impedance node domains arranged in the first direction. The rotor comb fingers are coupled to two oppositely biased electrodes to form oppositely biased domains. Pairs of capacitors with opposite acoustic polarity are respectively formed between the high impedance node domains and the oppositely biased domains. The comb drive of the present invention has increased electrostatic sensitivity for a given unit cell cross-sectional area whilst maintaining an acceptable capacitance and linearity of voltage signal vs displacement. Extra force shim unit cells may be used, which allows for the stiffness between the rotor and stator to be controlled and reduced to zero for a particular displacement range, without impacting sensitivity.Type: GrantFiled: August 13, 2021Date of Patent: June 13, 2023Assignee: AAC Acoustic Technologies (Shenzhen) Co., Ltd.Inventors: Anup Patel, Yannick Pierre Kervran, Euan James Boyd

Publication number: 20230059140Abstract: A microphone back panel and a microphone are provided. The microphone back panel is used for a microphone, the microphone includes a diaphragm, and the microphone back panel includes a main body. A side of the main body is provided with a thinned area not in contact with the diaphragm, and a hole is formed in the main body. The main body is provided with a thinned area, thereby increasing flexibility of the microphone back panel. When the microphone back panel is bent, the increased flexibility can reduce the stress load on the microphone back panel, thereby reducing possibility of damage to the microphone back panel. In addition, the main body is provided with a hole, thereby further increasing flexibility of the microphone back panel, and reducing stress load on the microphone back panel and reducing possibility of damage to the microphone back panel.Type: ApplicationFiled: August 20, 2021Publication date: February 23, 2023Inventors: Scott Lyall Cargill, Euan James Boyd
