摘要： A latch mechanism includes a mounting bracket, a stop connected to the mounting bracket, a first spring connected to the mounting bracket and in contact with the stop to preload the first spring, and a latch. The latch includes a second spring rotatably connected to the mounting bracket, and a body connected to the second spring. The body includes a pad at one end of the body, and a first pawl at a second end of the body opposite of the pad.

摘要： A device includes a syringe, which has a tip, plunger, and barrel containing a fluid. The device also includes a needle electrode coupled to the tip of the syringe, a release component, and a control component configured to receive electrical measurements made by the needle electrode, determine impedance values from the electrical measurements, and identify a target tissue based on the impedance values. In response to the identification, the control component generates instructions to reposition a release component. A method includes receiving electrical measurements from a needle electrode, determining impedance values based on the electrical measurements. A target tissue is identified based on the impedance values, and a release component is repositioned in response. An article of manufacture includes a needle electrode and a microprocessor configured to receive electrical measurements, determine impedance values, identify a target tissue based on the impedance values, and generate instructions to reposition a release component.

摘要： A process of utilizing a water-sensitive fluorophore for moisture content evaluation in a hygroscopic polymer includes forming a blend that includes a hygroscopic polymer resin and a water-sensitive fluorophore. The process includes forming pellets having a particular geometry from the blend, determining fluorescence properties of at least one of the pellets, and determining moisture content of at least one of the pellets. The process also includes generating a calibration curve for the particular pellet geometry by correlating the fluorescence properties with the moisture content. The process further includes providing the calibration curve for non-destructive moisture content evaluation of a material derived from the pellets.

摘要： Provided is a method for collecting sensor data using time-domain reflectometry (TDR). A primary device transmits a TDR signal to a first sensor. A reflected signal is received in response to the transmitted TDR signal. The reflected signal is analyzed to determine an impedance of the first sensor. Based on the impedance of the first sensor, a sensor value for the first sensor is determined.

摘要： A system and method for providing a secure image load. The system includes a microcontroller. The microcontroller has a plurality of physically modifiable internal components (PMIC). Each of the plurality of PMICs can only be modified one time. The system further includes an image loader configured to load a boot image from the memory of the microcontroller, and a checksum calculator configured to calculate a checksum value for the boot image. The system further includes a checksum burner configured to modify the plurality of PMICs to create a binary representation of the checksum value for the image. A checksum value is calculated for the image. This checksum value is written to the microcontroller. The value is burned into the microcontroller using the PMICs. Further, responses to the checksum mismatch are burned into the microcontroller using the PMICs that are present in the microcontroller.

摘要： Method, apparatus, and computer program product are provided for determining a maximum temperature to which a perishable good or other temperature sensitive item was exposed. In some embodiments, a capacitance of a circuit provided on a substrate is measured. The circuit includes capacitor(s) each having first and second plates separated from each other by an ionic liquid (IL) in a solid state. The IL melts at a predetermined temperature and flows away from the first and second plates into a void. In some embodiments, the predetermined temperature at which the IL melts is different for each capacitor. For example, each capacitor in the circuit may employ a different N-alkyl bezothiazolium salt. A maximum temperature of exposure is determined based on the measured capacitance. In some embodiments, a decision of whether to discard the perishable good or other temperature sensitive item may be based on the determined maximum temperature.

摘要： A lock system and method for alerting a user or other entity that a lock has been or is being tampered with is disclosed. The lock includes at least one enhanced security pin that is electrically isolated from the rest of the lock. When the lock picker attempts to pick the lock a portion of the enhanced security pin contacts either the plug or the outer casing of the lock to complete a circuit with an alert component. The completion of the circuit causes the alert component to generate an alert signal that can be observed by the user or other entity.

摘要： A process of curing a photo-curable material includes dispersing a microcapsule in a material that includes a photo-initiator and a photo-curable material. The process also includes applying a stimulus to the microcapsule to trigger a chemiluminescent reaction within the microcapsule. The chemiluminescent reaction generating a photon having a wavelength within a particular emission range that is consistent with an absorption range of the photo-initiator. The photon exits the microcapsule to trigger the photo-initiator to initiate or catalyze curing of the photo-curable material.

摘要： A method and circuit for implementing transient electronic circuits for security applications, and a design structure on which the subject circuit resides are provided. Silver nanowire traces are fabricated forming a protection circuit in a soluble material. A frangible material is provided separating the soluble material from a solvent layer proximately located. During a tampering event the frangible material is ruptured releasing the solvent which contacts and dissolves the soluble material and disperses the silver nanowire traces creating an electrical open in the protection circuit. The electrical open enables enhanced tampering detection.
