Abstract: An optoelectronic assembly which provides for enhanced alignment between the internal components thereof. The assembly includes a housing (17) having a base portion (19) and a cover portion (21), the housing including therein a circuitized substrate (27). A pair of optoelectronic devices (31, 33) (transmitter and receiver components) are initially movably (loosely) positioned within the housing. The invention utilizes an alignment member (110) which is secured to the housing while positively engaging the movably positioned devices and precisely align these devices with respect thereto such that these devices are in turn precisely aligned with optic means (e.g., a duplex optical connector) when the optic means is positioned within the alignment member. In one embodiment, the housing is of metallic material while the alignment member is a molded plastic structure. The alignment member may also include shutter means therein for safety purposes.

Abstract: A computer system, and particularly a handheld mobile client system, in which a user input device such as a keyboard or a scanner, coupled by a tethering conductor or a wireless link such as an infrared radiation link, functions as a master while the central processing unit of the system functions as a slave in receiving input digital signals.

Abstract: A serial port, input/output controller and central processing unit of a computer 10 co-operate to detect and identify a user input device connected to the serial port and to establish the input device as a master governing functioning of the central processor unit. The input/output controller translates scan code signals from the user input device. The computer may be a mobile client comprising a holster 12 which accommodates a tablet 11 and a cellular telephone for communication with a server 20. The tablet has a liquid crystal display with a touchscreen 15 and an optional keypad (Fig 3). User input may also be via a keyboard 16 or bar code scanner 17 attached to the serial port.

Abstract: A new fiber optic connector housing and a new fiber optic receptacle, both of which conform to a new standard proposed by the X3T9.3 committee of the American National Standards Institute, are disclosed. In addition, four accessory devices for electro-optic modules, each of which includes one or more essentially conventional plug frames which fit into either one or more conventional, individual fiber optic connector housings or the new fiber optic connector housing, are disclosed.
