  • Patent number: 11779517
    Abstract: A medication bottle includes an outer container wall, an inner container wall and a fluid, such as an aversive liquid, located between the walls. In another aspect, the fluid is located within separate compartments or channels located between the walls where the walls contact or are secured to each other. A further aspect provides a removeable cap including multiple sensors, at least one of which is a biometric sensor.
    Type: Grant

  • Patent number: 11568193
    Abstract: This disclosure is generally directed to an RFID system that includes a hybrid RFID tag offering a functionality of a passive RFID tag and an active RFID tag. When operating as a passive RFID tag, an RF signal received from an RFID reader is harvested to produce a DC voltage for powering the hybrid RFID tag. The harvested DC voltage is coupled into a capacitor at a slow-charging rate so as to avoid a capacitor inrush current causing an abrupt power supply voltage drop. A controller chip in the hybrid RFID tag can execute some RFID functions at this time, thereby speeding up a response to the RFID reader. The capacitor is then charged at a fast-charging rate for storing a reserve charge. The hybrid RFID tag can subsequently use the reserve charge to operate as an active RFID tag without waiting for an RF signal from the RFID reader.

  • Patent number: 6998613
    Abstract: A method for forming an integrated circuit includes providing an array of detectors proximate an outer surface of a first substrate layer. The array of detectors operate to detect the presence or absence of one or more wavelengths within a spectrum of transmitted energy. One or more filters are provided proximate a second substrate layer. The one or more filters operate to affect the spectrum of transmitted energy through the one or more filters. The second substrate layer is proximate to the outer surface of the first substrate layer to enclose the array of detectors in a vacuum environment.
