Publication number: 20220013834Abstract: Battery systems according to embodiments of the present technology may include a battery cell having an electrode tab extending from an edge of the battery cell. The systems may also include a module electrically coupled with the battery cell. The module may be characterized by a first surface, a height, and a second surface opposite the first surface. A conductive tab coupled along the first surface of the module may extend from a first end parallel to a plane of the first surface. The conductive tab may be characterized by a curvature proximate a midpoint of the conductive tab. A distal region of the conductive tab may return back across the first surface of the module substantially parallel to the first surface. A distal portion of the electrode tab may be fixedly coupled with the distal region of the conductive tab.Type: ApplicationFiled: September 24, 2021Publication date: January 13, 2022Applicant: Apple Inc.Inventors: Angelo V.

Patent number: 5012442Abstract: A bus receiver power-up synchronization circuit synchronizes the receipt of parallel data messages transferred asynchronously as three byte words preceded and succeeded by idle bytes so as to receive complete and not partial messages. Also, the receiver scrutinizes the messages for faults and for too many or too few bytes.Type: GrantFiled: December 19, 1988Date of Patent: April 30, 1991Assignee: Chrysler CorporationInventor: John M. McCambridge

Patent number: 4977559Abstract: Combinational logic circuits are used with a temporary storage device holding data bytes to detect improper bits in both the lower and upper nibbles of the bytes. Combinations of bit patterns derived from both nibbles permit flagging the occurrences of a variety of bit errors existing in sequentially transmitted parallel data bytes.Type: GrantFiled: December 19, 1988Date of Patent: December 11, 1990Assignee: Chrysler CorporationInventor: John M. McCambridge

Patent number: 4930094Abstract: A method and firmware/hardware system for updating an analog odometer using a pulse rate rather than an absolute number of updating pulse signals. The pulse rate is developed from a number that represents an accumulation of a series of pulses that represent distance traveled by a vehicle during a chosen interval.Type: GrantFiled: July 11, 1988Date of Patent: May 29, 1990Assignee: Chrysler CorporationInventors: William V. Luitje, John M. McCambridge

Patent number: 4754466Abstract: A digital pulse width modulator for generating output frequencies with adjustable pulse widths that can be controlled by a microcomputer interface. A method to perform a DPWM chip select and to control the latching, shifting and counting of DPWM counters and registers is also presented. This allows the traditional uses of PWMs to enter the realm of microcomputer systems.Type: GrantFiled: May 22, 1986Date of Patent: June 28, 1988Assignee: Chrysler Motors CorporationInventor: John M.

Patent number: 4739323Abstract: The aim of the Chrysler Collision Detector (CCD) Bus System is to allow multiple microprocessors to easily communicate with each other over a common pair of wires (called a bus) using a scheme similar to a telephone party line. All microprocessors connected to the bus are able to receive all messages transmitted on the bus. Any microprocessor with a message to transmit on the bus waits until any current user is finished before attempting to use it. Whenever the bus is available, its use is allocated on a first-come, first serve basis (i.e., whichever microprocessor first begins transmitting its message on the bus after any previous message finishes gets the use of the bus). If, however, multiple microprocessors attempt to begin transmitting their messages on the bus at exactly the same time, then the message with the highest priority wins the use of the bus. All messages have unique message priority values and each message is transmitted by only one microprocessor.Type: GrantFiled: May 22, 1986Date of Patent: April 19, 1988Assignee: Chrysler Motors CorporationInventors: Frederick O. R. Miesterfeld, John M. McCambridge, Ronald E. Fassnacht, Jerry M. Nasiadka

Patent number: 4706082Abstract: A bus interface integrated circuit is presented which utilizes an arbitration detector, a collision detector and a contention permitting differential transceiver to work with a serial communication interface port on a microprocessor to determine between contending messages which message gains access to the communication bus by using the value or priority of the ID byte without losing bus time.Type: GrantFiled: February 24, 1986Date of Patent: November 10, 1987Assignee: Chrysler Motors CorporationInventors: Frederick O. R. Miesterfeld, Ronald E. Fassnacht, John M. McCambridge
