Abstract: Flexible and scalable systems and methods for charging electric vehicles (EVs) are disclosed. For example, a system may be configured to dynamically adjust the amount of power available to one or more EVs based on real-time measurements of a residential load. In some implementations, the system may be configured to ensure that the combined load of the EVs and the residential load does not exceed a predetermined threshold. The predetermined threshold may be based on the power capacity and electrical specifications of an existing building. As a result, the system can be added to an existing building without overloading the grid and/or without significantly altering the power infrastructure of the building.

Abstract: An electrical connector comprises a plug and socket electrical connector which includes two contact inserts each of which is separately adapted to be snap-fitted and held within a backing shell. The contact inserts can be joined together to form an electrical connection, and are held together by a first locking mechanism such as a bayonet and socket arrangement. A second locking mechanism is provided comprising a mated pair of coupling rings which are adapted to surround the contact insert connection.

Abstract: A bidirectional lens pressing system for use in pressing a lens into a port housing is disclosed. The lens pressing system includes a frame that supports a top motor stage, a bottom motor stage, and an indexing stage. The indexing stage is interposed between the top and bottom motor stages and includes a hole that retains a port housing or other component. The top pressing tool is selectively movable in a first direction by the top motor stage and includes a first engagement surface for engaging the lens. Correspondingly, the bottom pressing tool is selectively movable in a an opposing second direction by the bottom motor stage and includes a second engagement surface for engaging the port housing. The first and second engagement surfaces of the top and bottom pressing tools cooperate to press the lens into the port housing while imposing no net force on the indexing stage.

Abstract: A system for actively aligning an optoelectronic device including a frame, a mounting and alignment assembly, and a camera. The mounting and alignment assembly can be movably connected to the frame and is configured to mount separate portions of an optoelectronic device such that the portions can be moved in relation to each other. An optical signal from a laser in the first portion is transmitted through an optical element in the second portion and captured by the camera to determine the positioning of the first and second portions of the optoelectronic device. The portions can then be aligned accordingly.

Abstract: A shield device for preventing the emission of electromagnetic interference (“EMI”) from an optoelectronic device, such as an optical transceiver, is disclosed. In particular, an EMI shield is disclosed for placement within an optical transceiver module in order to intercept and absorb EMI produced by electronic components included within the transceiver. This absorption by the EMI shield prevents EMI from escaping the optical transceiver module and interfering with other electronic components that are typically placed in close proximity to the transceiver. The EMI shield in one embodiment includes a sheet of EMI absorbing material that is sized for placement within the transceiver. The EMI shield can be interposed between an outer shell of the transceiver and electronic components located on a printed circuit board that is disposed within the transceiver. The proximity of the EMI shield to the EMI-producing electronic components maximizes EMI absorption by the shield.

Abstract: An antenna arrangement (402) for a wireless communication device (400) comprises a first element (404) and a second element (406). The first element (404) is coupled to circuitry (408) of the wireless communication device (400). The second element (406) is movable between a first and a second position relative to the first element (404). The performance of the antenna arrangement (402) is substantially less desirable when the second element (406) is between the first and the second position than the performance of the antenna arrangement (402) when the second element (406) is at either the first or the second position. The second element (406) is mechanically spaced apart from and substantially electrically coupled to the first element (404) in both the first and the second position. The antenna arrangement (402) advantageously provides for reduced dimensions while achieving desirable performance.

Abstract: A wireless communication device (101), such as a radiotelephone or a pager, comprises a signal generator (200), a radiator (202), a sensor (204) and a controller (206) to form an electromagnetic wave proximity sensor (201). The signal generator (200) generates a signal (210). The radiator (202) radiates the signal (210) to produce an electromagnetic field (212) near the radiator (202). The electromagnetic field (212) changes by a predetermined amount responsive to the proximity (214) of the radiator (202) to a predetermined object (216), such as a human body (232), external to the wireless communication device (101). The sensor (204) provides an indication (218) of the predetermined amount of change in the electromagnetic field (212). The controller (206) controls circuitry (208), such as a tactile alert device (416) and an audible alert device (418), in the wireless communication device (101) responsive to the indication (218) of the predetermined amount of change in the electromagnetic field (212).
