Abstract: A container for pharmaceuticals such as pills and tablets has an RFID chip embedded within its wall. The chip preferably transmits and receives at a frequency of approximately 24 GHz. When the container is formed of a thermoplastic, the chip is preferably injected into the soft sidewall of the thermoplastic while it is at an elevated temperature and still in a moldable state. For a glass container, a recess is molded in the wall of the container of an appropriate size to accommodate the chip and after molding the chip is secured within the recess with an adhesive and may be covered to prevent tampering. The memory of the chip stores the nature and quantity of elements stored in the container. By weighing the container after a portion of the contents have been removed, the stored quantity in the chip may be modified.

Abstract: A system for controlling gemstones employs RFID chips adhered to each stone. A display or storage area includes a radiator for generating activating emission for the RFID chips and an antenna for picking up the resultant RF signals including serial number. Both the radiator and antenna are connected to a computer supporting a database with an inventory of the chips and anti-collision circuitry for identifying the chips.

Abstract: An improved tympanic thermometer incorporates twin thermopiles, each including a set of sensing junctions and a set of reference junctions configured so that three of the four sets of junctions sense only the temperature of an ambient environment, while the fourth set of junctions receives energy from both the ambient environment and from the tympanic membrane of a patient whose temperature is being taken. The energy received from the tympanic membrane is intentionally not bandwidth limited, enabling an accurate temperature measurement to be calculated which is substantially independent of wavelength. A light pipe is optionally included to assist in carrying radiation from the tympanic membrane to the fourth set of thermocouple junctions used for temperature sensing. In the preferred embodiment a dielectric coating is internally applied within the light pipe, and interchangeable tubes may be provided which conform to the aural physiology of different patients, including children.

Abstract: A calculator apparatus 10 includes the standard calculator mode and several other modes functions namely; a pressure-temperature conversion, a temperature-to-pressure conversion based on refrigerant, a relative humidity reading based on input of the dry bulb and wet bulb temperature; and a flow-energy rate conversion mode based upon a selected fuel meter dial and Metric or English units. In addition, a Fahrenheit-to-centigrade conversion and a centigrade-to-Fahrenheit conversion functions are incorporated. The calculator includes a keyboard 18, a microprocessor 16, a timer 26, a power source 12, a switch 14 and a display screen 22.
