Patent number: 11724425Abstract: A micro moulding machine and process for forming small plastic parts for the medical device industry. The machine adds heat in two steps to a precision sized plastic pellet and then displaces the entire pellet volume into the mould cavity. A substantial amount of heat is added to the pellet by forcing it through an orifice very near the gate of the mould. The pneumatic pressure to drive the pellet through the orifice is controlled to regulate the amount of heat introduced into the pellet.Type: GrantFiled: November 5, 2020Date of Patent: August 15, 2023Assignee: Minnesota Micro Moulding Machine and ProcessInventors: Jon Baklund, Alex Madsen

Publication number: 20230021324Abstract: An electrical device including a surface which may be exposed to heat derived from operation of the electrical device such that the temperature of the surface increases during operation. The surface includes a temperature sensor including first and second electrodes separated by a layer of control material. The material properties and/or configuration of the control material are selected such that the electrical conductivity of the control material increases with increasing temperature so that electrical current is able to pass between the first and second electrodes once the temperature of any part of the control material has reached or exceeded a predetermined temperature. The temperature sensor extends over substantially the whole of the surface. A system including the electrical device and a method of controlling the electrical device is also disclosed.Type: ApplicationFiled: December 4, 2020Publication date: January 26, 2023Applicant: Dyson Technology LimitedInventors: Ian Andrew HUNT, Alex MADSEN

Publication number: 20230019975Abstract: A battery cell including an electrode assembly contained within a housing. The electrode assembly shrinks and/or swells depending on a charge/discharge cycle of the cell. A swelling compensation member configured to shrink upon swelling of the electrode assembly, and expand upon on shrinking of the electrode assembly is in continuous contact with the electrode assembly and an innermost surface of the housing. A first portion of the innermost surface of the housing is in contact with the swelling compensation member, and a second portion is free from contact with the swelling compensation member. The battery cell includes a cooling member in thermal contact with the outermost surface of the housing. Part of the outermost surface of the housing in contact with the cooling member corresponds to a part of the innermost surface of the housing which is free from contact with the swelling compensation member.Type: ApplicationFiled: December 4, 2020Publication date: January 19, 2023Applicant: Dyson Technology LimitedInventors: Ian Andrew HUNT, Alex MADSEN

Patent number: 9030222Abstract: An apparatus and method providing improved interconnection elements and tip structures for effecting pressure connections between terminals of electronic components is described. The tip structure of the present invention has a sharpened blade oriented on the upper surface of the tip structure such that the length of the blade is substantially parallel to the direction of horizontal movement of the tip structure as the tip structure deflects across the terminal of an electronic component. In this manner, the sharpened substantially parallel oriented blade slices cleanly through any non-conductive layer(s) on the surface of the terminal and provides a reliable electrical connection between the interconnection element and the terminal of the electrical component.Type: GrantFiled: August 6, 2010Date of Patent: May 12, 2015Assignee: FormFactor, Inc.Inventors: Benjamin N.
