A solar cell apparatus and process for making and using same involving a semiconductor wafer having a front side surface and a metallized back side surface and a semiconductor p/n junction between the front side surface and the back side surface. At least one front side interruption is caused to extend along at least a portion of the front side surface and into the wafer to a depth sufficient to interrupt the semiconductor p/n junction to define a plurality of separate p/n junction sections within the wafer and to define separate front side surface portions associated with respective separate p/n junction sections. A back side interruption is caused to extend along a portion of the metallized back side surface, generally opposite the front side interruption, to define a plurality of separate metallized back side surface portions associated with respective p/n junction sections and in electrical contact with respective p/n junction sections.

A photovoltaic apparatus has a semiconductor photovoltaic cell structure having a front surface and a back surface provided by respectively doped portions of semiconductor material forming a photovoltaic junction. A plurality of separate electrical contacts is embedded in the front side surface of the respective one of the portions of semiconductor material. The electrical contacts are distributed in two dimensions across the surface and are separated from each other and are in electrical contact with the respective one of the portions of semiconductor material. A back side electrical contact is provided on the back surface of the other of the respective portions of semiconductor material and in electrical contact therewith. A solar cell apparatus includes the apparatus above and electrodes for contacting the electrical contacts on the front and back side surfaces respectively of the semiconductor material.

An automatic decompression device for an internal combustion engine includes a camshaft rotatable about an axis of rotation and having an end face, and a lever coupled to the end face and movable between a first position, wherein the lever is engageable with a valve actuating device to actuate a valve during rotation of the camshaft, and a second position, wherein the lever does not substantially move the valve actuating device. The lever is preferably pivotally coupled to the end face to pivot about a pivot axis that is substantially perpendicular to the axis of rotation of the camshaft. Further preferably, the automatic decompression device further includes a spring between the end face and the lever to bias the lever toward the first position. In a highly preferred embodiment, the end face of the camshaft includes a slot and the lever is at least partially retained within the slot.

A center console for a motor vehicle has a basic body between the front seats with an upwardly open storage compartment over which a support part having an armrest which is displaceable with respect thereto is arranged. The armrest is displaceable from a pushed-back position between the front seats in the direction of the dashboard into a front position, wherein the support part is mounted pivotably on the basic body. The locking mechanism is provided with an actuating element via which, by an different actuation, a pivoting movement of the armrest together with the support part and a displacement movement of the armrest relative to the support part can be released. The locking mechanism is configured such that it permits a pivoting movement of the armrest together with the support part exclusively if the armrest is in its completely pushed-back position.

Techniques are described to enable a user to define data-transition rules that control how a handover component of a computer application transforms business objects of one type to business objects of another type. The handover component is logically situated between a preceding business process that uses a preceding type of business object and a second business process that uses a second type of business object. Based on the user-defined data-transition rules, the handover component performs a split/merge process that determines the succeeding business objects to be generated based on the preceding business objects received from the preceding business process and then generates the succeeding business objects based on the received preceding business objects and the user-defined data-transition rules.
