An improved printed circuit board which can reduce or eliminate unsatisfactory soldering caused by trapped gas in surface mounting electronic components by flow soldering is disclosed. According to the invention, the printed circuit board comprises an electrically conductive pattern having a plurality of connection pads to which leads of electronic components are to be connected; and a solder resist layer formed over said electrically conductive pattern and having a plurality of windows which expose said connection pads, wherein at least one of said windows has an extension exposing an additional part of said pad, said extension being substantially narrower than said window. The extension allows the additionally exposed part of the pad to contact with the solder even when the associated pad is almost entirely covered by the trapped gas, so that the solder is pulled to the pad and spread over the pad. Because the extension require a small area, it is effective even when the components are mounted at a high density.

A device which enables a driver of a vehicle to monitor an infant in a rear seat by the rear view mirror of the vehicle, where the device is portable, universally applicable to passenger vehicles and non-destructive of the vehicle interior yet secure against vehicular vibration. The device consists of a threaded telescoping mast having a mirror for viewing the infant which mast is positioned between the top of the backseat and the headliner and secured by outward pressures developed by a wing nut positioned on the mast.

An auxiliary rear view mirror assembly for increasing a driver's lateral and rearward field of vision without adversely affecting the driver's forward field of vision. The auxiliary rear view mirror assembly is mounted at the rear of a vehicle in a location which is visible in a main rear view mirror of the vehicle. The auxiliary rear view mirror assembly is comprised of a pair of auxiliary rear view mirrors which are independently selectively adjustable about a pair of axes and selectively adjustable about a second axis which is in orthogonal relationship to the first pair of axis. In a first embodiment, the auxiliary rear view mirror assembly is mounted on a rear window of the vehicle. In a second embodiment, the auxiliary rear view mirror assembly is mounted on a rear brake light. In a third embodiment, the auxiliary rear view mirror assembly is combined with a rear brake light and is remotely adjustable by a set of controls which are accessible to the driver.

An assembly for observing an infant in a rear facing child safety seat located on a rear seat of a motor vehicle which includes a mirror and a mirror support arm. The mirror support arm includes a base or lower portion that is configured to be coupled to a child seat or otherwise held in position thereby. An upper portion of the mirror support arm includes a portion that is configured to secure the mirror thereto in an adjustable manner, so that the mirror can be aligned to provide a person sitting in a front seat of the motor vehicle with a line of sight to the infant which line of sight that is directed off the mirror and a rear view mirror that is provided in the front portion of the motor vehicle.

A device which enables a driver of a vehicle to monitor an infant in a rear seat by the rear view mirror of the vehicle, where the device is portable, universally applicable to passenger vehicles and non-destructive of the vehicle interior yet secure against vehicular vibration. The device consists of a non-threaded telescoping mast that is held into a selected position by a clip, and a mirror for viewing the infant which mast is positioned between the top of the backseat and the headliner secured by outward pressures from a backseat pad and an upper pivotal pad. The pivotal pad can be attached to the mast by a ball and socket for allowing 360 degrees of pivot.
