Abstract: A system for monitoring ambient temperatures surrounding a child's car seat and alerting a user of unsafe highs or lows includes a battery and a microcontroller mounted within a housing. The microcontroller includes a transmitter that communicates with a temperature sensor and an external server. The transmitter and the temperature sensor each have an active state and a resting state. In the resting state, the components draw little to no power from the battery. The temperature sensor periodically enters the active state to take ambient temperature readings. When those ambient temperature readings fall outside of the predetermined ranges for child safety, the transmitter enters the active state and sends an alert to the server, which relays the alert to the user. The transmitter can also send the alert to an emergency communications line or emit an audible alarm to alert nearby people of the unsafe conditions.

Abstract: A Seebeck effect renewable energy arrangement can be used to generate electricity due to temperature differences. The Seebeck effect renewable energy arrangement includes an environmental arrangement, a ground arrangement, and a power output arrangement. The environmental arrangement is connected to the ground arrangement to create an electrical circuit such that the temperature difference between the environmental temperature and the ground temperature generates electricity due to the Seebeck effect. The power output arrangement is operatively connected to the circuit to conduct electricity generated thereby to storage or use to power electrical devices.

Abstract: A voltage level shifting circuit (10) transitions an input signal at a first voltage to a second voltage higher than the first voltage. A cross-coupled latch provides the second voltage. Cascode configured transistors (16, 26) are connected in series with input transistors (18, 28) that receive the first voltage in complementary form. Capacitive devices (34, 40) are connected between the first voltage and gates of the cascode configured transistors for allowing independent small signal variations to occur on the gates of the cascode configured transistors for better control of duty cycle and rise and fall time matching of the level shifting circuit. Isolation devices (32, 38) permit independent modification of small signal voltages to occur on the gates of the cascode configured transistors.

Abstract: A barrel shifter comprises a first plurality of bit lines, a second plurality of bit lines and a plurality of switchable interconnections therebetween. A first subset of the switchable interconnections provide each of a set of desired shifts, while a second subset of the switchable interconnections duplicate certain of the first subset thereof and shorten the worst-case path lengths through the shifter. The first and second pluralities of bit lines may comprise interleaved high- and low-order bit lines of two data buses. Interface means may provide the interleaving function and also may provide means for accomplishing at least one shift in addition to the set of desired shifts. Sense amplifiers may be included for sensing voltage transitions on each bit line.
