Method and system to collect measurements from multiple metering devices. The collector devices store and forward measurement information through a network connection to a remote processing center to generate an output based on the measurement information.

A three-dimensional stacked semiconductor package device includes first and second semiconductor package devices and a conductive bond. The first device includes a first insulative housing, a first semiconductor chip and a first lead that is bent outside the first insulative housing. The second device includes a second insulative housing, a second semiconductor chip and a second lead that is flat outside the second insulative housing. The conductive bond contacts and electrically connects the leads.

A camera system for monitoring a space area has a camera unit including an image sensor and a number of optical elements which form an imaging optics. A system body has at least one receptacle for the camera unit. A mounting part serves for aligning the system body relative to the space area. The optical elements are fastened on an objective body which has a mounting flange. The objective body is fastened in the receptacle by means of the mounting flange.

A method of manufacturing a solar cell by providing a first substrate; depositing sequentially on the first substrate a plurality of semiconductor layers, the plurality of semiconductor layers comprising a first layer and a last layer in the direction of deposition; forming a backside contact layer on the last semiconductor layer; forming on the last semiconductor layer a back cathode contact isolated from at least a first portion of the backside contact layer, the first portion forming the anode contact; attaching a second substrate on the backside contact layer and removing the first substrate to expose the first semiconductor layer and to define a front surface and an opposite back surface of a solar cell; forming a front cathode contact on the front surface of the solar cell; etching a first trench through the plurality of semiconductor layers to define an active portion of the solar cell with a first mesa structure including the front cathode contact and the anode contact and being surrounded by the first trench, the first mesa having a first sidewall in the first trench and a lateral peripheral region beyond the sidewall, and forming in the lateral peripheral region an electrically conductive layer extending from the front surface where it is electrically connected to the front cathode contact along the first sidewall of the first trench to be electrically connected to the back cathode contact.

A system for preventing overflow of a toilet includes a sensor, a processor and an actuator. The sensor senses a parameter caused by fluid dynamics within the toilet during a flush cycle. The parameter may involve vibration, sound, pressure, fluid flow rate or other detectible characteristics of the toilet. The processor uses information regarding the parameter that is gathered by the sensor to evaluate the condition of the flush cycle to determine if an impeded flush condition exists. In the event of an impeded flush condition, the processor directs the actuator to close a valve, which may be the toilet flapper valve in some embodiments. Also disclosed are methods for preventing toilet overflow, detecting an impeded flush condition and calibrating the system.

The present invention provides a process for forming a composite material. The present invention further provides methods of improving the fiber volume fraction and/or the dimensional thickness of a composite panel.

The present invention relates to a measurement-while-drilling tool [2] with a mechanically driven poppet [216] which eliminates the flow of drilling fluid through the tool, and reliance on surface supplied hydraulic force to activate the poppet [216]. The present invention eliminates the pilot valve system, and generates a fluid pulse from a direct drive relationship between a reversible motor [414], actuator [300], and poppet valve [216]. A pulser [200] has a push rod [214] slidably located inside. Poppet [216] is located on the push rod [214]. Actuator [300] is connected to the pulser [200], and has a ball screw [334] mechanically connected [330] to the push rod [214]. An electric motor [414] and gear train is operatively connected [338] [340] [342] to the ball screw [334]. Motor [414] generates linear movement of the poppet [216] in relation to an orifice [112] to restrict flow and generate a pulse.
