Abstract: A zero-insertion force socket connector that mates with a standard pin connector with zero insertion force. An actuation mechanism built into the socket connector, actuated after mating creates a level of contact force necessary to establish good electrical contact. The socket actuation is designed such that the socket contact does not exert any compression force on its mating pin contact during mating. This helps eliminate potential buckling of slender contact pins when large contact force is required. The socket design works with a standard pin contact such as the one, on every electric vehicle. Thus, the invention allows connecting to an existing electric vehicle without any modification, with zero insertion force, yet delivers the necessary contact force and preserves the long-term integrity of the connector pins by eliminating potential pin buckling during mating.

Abstract: The invention teaches how to establish 1 to 1 connection between a first group of n electrical signals to a second group of n electrical signals. A first connector half with a first group of n1 contacts equally spaced around a circle and a second connector half with a second group n2 connectors, also equally spaced around a circle, with n1?1=n2?n. The angular extent of the individual contacts from the first group is e1, and that from the second group is e2. The angular extent of the gap between individual contacts from the second group is g2. Following relationship must be satisfied: e1<g2 and e2>(360/n1?e1). A switch interconnect means for connecting arbitrarily selected n contacts out of a first group of n1 contacts where (n1?1) n to n signals from a first group of n signals. The minimum number of signals required for doing this is n+(n1?n)*n.

Abstract: An apparatus, system, and method for conductive coupling for contact charging and method for safe decoupling. A first interface for transferring electrical energy to or from a mating interface. The first interface comprises a plurality of connectors coupled together. The plurality of connectors further comprises one or more of a first type of connector; and one or more of a second type of connector. In one embodiment, at least one physical property of each of at least one of the first type of connector is unequal to at least one physical property of each of at least one of the second type of connector. The first interface and the mating interface are selectively decoupleable from each other in a plurality of directions.

Abstract: In the modern world, electricity has become ubiquitous. Electrical connectors that connect and disconnect the electricity from the end use device have become important. If the connector has established a good quality contact across its mating conductors, there is no cause for concern. Also, if the connector has not established any contact with associated contacts being far away, then also there is no cause for a safety concern. However, when a connector has established marginal contact between the source and drain side contacts, and if the load and the source are switched on, the possibility of an arc across the thin layer of oxide separating the two contacts is high. This invention teaches a method to measure the quality of electrical connection established across an electrical connector. The method described here can be used to ascertain the quality of the connection before turning on the current across the connection.

Abstract: This patent teaches a novel approach to deliver sufficiently high force at the end effector of a robot, without making the overall robot bulky. Instead of transferring the force at the end effector to the predecessor link, the innovative approach taught in this patent consists of transferring the end effector's force directly to ground or to a suitable frame such as conveyer frame in case of spot welding application. Many times, a ground or suitable frame may not be available to transfer the force, but many other times, there is such a frame available, and the technology described in this patent can become critical in designing a compact, lightweight robotic arm and may make a difference between having a viable product or not.

Abstract: The invention teaches a zero-insertion force socket connector that allows mating with a standard pin connector with zero insertion force. An actuation mechanism built into the socket connector is actuated after mating to create a high level of contact force necessary to establish a good electrical contact. The novel method for socket actuation is designed such that the socket contact does not exert any compression force on its mating pin contact—as is the case for a typical pin & socket joint. This helps eliminate buckling of slender contact pins when large contact force is required. The novel socket design allows it to work with a standard pin contact, which could be defined as a standard required connector provided on—for example, on every electric vehicle.

Abstract: This invention teaches a connector design that has the capability to safely disconnect the power flowing through the connector when misalignment of the two connector halves is detected. Monitoring contactors disposed on different locations on the connector and are made to carry or not-carry (depending the contact position in the connector), a pilot signal generated by one of the connector halves. The presence or absence of the pilot signal on the individual contacts is monitored by the other connector half. A safe and automatic power disconnects ensues when the two connector halves misalign. This happens well before the primary power contact disengage. The clever design detects not only in-plane misalignments, but also out of plane misalignments.

Abstract: The general field of this invention is electrical connectors and their actuating mechanism. More specifically, this invention teaches a novel connector and its actuating mechanism for establishing an electrical connection between two arbitrarily oriented objects such as an arbitrarily parked EV and infrastructure. In most of the prior art, a conductive connection requires precise and guided alignment of mating conductors. The prior art achieves this either by a sensor guided search or mechanical guides to being the two objects into desired alignment. In order to tolerate a wider misalignment between the two objects, the guides have to have a large footprint. In contrast, this invention breaks down the process of aligning the two halves of connector into a series of simple motions—when carried out in a particular order, would deliver the necessary alignment of the two sides of a connector.

Abstract: The general field of invention is electrical connectors and their conductor geometry. This patent teaches how to make the register-free charge couplers to have self-cleaning ability as well as tolerating operation under dirty environments such as underbelly of cars, while still delivering the requirements imposed by the register-free functionality. Although this invention can benefit many connector designs and applications, it is particularly beneficial when applied to hands free connectors for charging electric vehicles—also known in the industry as the Electric Vehicle Charge Couplers. The specific geometry taught in the patent satisfies the requirements of register-free connectors such as not to be able to short circuit supply conductors, provide at least one drain side conductor for every supply side conductor, permit easy sliding between supply and drain side conductors and provide at least one drain side contact with its centerline to overlap each supply side contact.

Abstract: A mechanical, electrical and telecommunication system to electrically connect a vehicle to an electricity source to transfer energy to the vehicle is presented. The system is designed to tolerate misalignments of a parked vehicle with respect to the parking stall. An important component of the system is a pair of rigid, insulating strips with a series of conductors on each of them, placed at approximately right angles to each other. One of the strips is mounted on the infrastructure or road side and the other on the vehicle. The two strips cover the lateral and longitudinal misalignment of the parked vehicle. As long as the two strips have a cross point; the connection can be made by the conductors in the overlap region. The system is designed to operate only in the active presence and active desire of a vehicle to connect to the infrastructure or road side stationary part.
