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 dynamic password authentication system and the method thereof are disclosed. According to one aspect of the present invention, a dynamic password telecommunication card embedded with a security algorithm in the SIM card of a mobile telephone is used to generate a momentarily changed password. The technique as disclosed improves the security of identity authentication effectively and avoids the trouble for the user to remember the password and change the password frequently. The technique is also suitable to a systems that requires a higher security of the identify authentication, such as the bank, the securities, the police and the electronic government affair and the like, thereby to improve the security for the system administrator and the user to login the system.

The conductive bond contacts and electrically connects the leads.

A region of flexure layer, including slider mounting face coupled to offset mounting face for at least one piezoelectric device. The offset mounting face for piezoelectric device provides asymmetry between first contact region and second contact region. This is cost effective, reliable support for piezoelectric devices used for micro-actuation in hard disk drives. The slider moves based upon asymmetry of the offset mounting face coupled to the piezoelectric device twisting the slider mounting face. The invention includes flexure containing the region of the flexure layer. The invention includes head gimbal assembly including flexure, actuator arm including head gimbal assembly, and actuator assembly including actuator arm, and hard disk drive including actuator assembly. The invention includes manufacturing the region, the flexure, the head gimbal assembly, the actuator arm, the actuator assembly and the hard disk drive, as well as these products of the manufacturing processes.

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.

An RFID smart label includes a plurality of layers, wherein one of the plurality of layers is an RFID inlay with a depression/recession region for holding the RFID chip/strap so that it does not extend above the surface of the antenna. The depressed/recessed region can have substantially the same depth as the thickness of the RFID chip/strap. High speed printing processes are then used to economically print labels on the RFID inlays having the RFID chip/strap embedded because there are no bumps to impede the printing process. A method for reliably and economically manufacturing a radiofrequency identification (RFID) antenna includes impressing a pattern on a surface of a substrate to make a first portion of the substrate having a positive image of the RFID antenna and a second portion of the substrate having a negative image of the RFID antenna, applying a release agent on the second portion of the substrate having a negative image of the RFID antenna, depositing a metallization layer over the surface of the substrate, applying a solvent over the metallization layer, and scraping the surface of the substrate causing mechanical interruption of the metallization layer. The release agent can be masking materials containing TiO₂ or oil.

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.
