The invention provides a sensor including a first sensor element formed in a first substrate and at least one optical element formed in a second substrate, the first and second substrates being configured relative to one another such that the second substrate forms a cap over the first sensor element, the at least one optical element being configured to guide incident radiation on the cap to the first sensor element. The sensor also includes a reference sensor element whose output can be used to reference the output of the first sensor element.
摘要:
The invention provides a sensor array having a plurality of sensor elements formed in a first substrate and having a plurality of die temperature sensors located thereabout. Each of the die temperature sensors are configured to provide an output related to the temperature of the die on which they are located, the sensor elements providing an output indicative of the intensity of radiation incident thereon.
摘要:
The invention provides a sensor element formed in a first substrate and having a thermal barrier disposed between the sensor element and a heat source provided elsewhere on the first substrate. The thermal barrier includes at least one pair of trenches formed within the first substrate, individual trenches of the pair being separated by a cavity.
摘要:
A method of quickly and accurately associating a customer name and address with a unique RFID identification tag to be used on a waste or recyclable materials container by the customer. A self-adhesive RFID label including an embedded RFID identification tag is provided in an envelope. Using a hand-held RFID tag reader or more preferably, an RFID reader mounted in a printer coupled to a computer device, a customer name and address is selected from a database and printed on an envelope or directly on the RFID label. Using the RFID reader in the printer and while the customer name and address is being printed, the unique RFID identification number from the RFID identification tag is read, provided to the computer device and automatically inserted into the customer database record, thereby associating the unique RFID identification tag number with the customer record. The RFID label is then delivered (mailed) to or picked up by the customer, all without need to send someone to a customer site to read the RFID tag associated with a waste or recycle bin and associated with the customer record. The customer can then easily apply the self-adhesive label with the RFID tag to their appropriate waste or recycle container.

A galvanically isolated signal conditioning system includes a signal conditioning circuit on an integrated circuit chip; a flying capacitor; and a galvanically isolating MEMS switching device on an integrated circuit chip for selectively switching the flying capacitor from across a pair of input terminals in one state to across the input terminals of the signal conditioning circuit in another state.
摘要:
A capacitive sensor including a housing having a hermetically sealed cavity, a plate in the cavity, a diaphragm forming a part of the cavity and spaced from the plate, a conductive layer on the first diaphragm, and a second conductive layer on the plate, the first and second conductive layers being the electrodes of a capacitor whose capacitance varies with the position of the diaphragm relative to the plate.
