Certain embodiments of the present invention relate to a dynamic power management system. The system includes a power input providing power to an imaging system, measurement unit(s) for measuring current and/or voltage in the imaging system, and a power management controller allocating available power among components in the imaging system. The power management controller may allow a battery to charge at a maximum rate based on current used by the imaging system components. The measurement unit(s) may measure a voltage and a current for the power provided to the imaging system. The power management controller may control current drawn by the imaging system components. The system may also include a limit sensor for detecting when current consumption exceeds a certain limit. Additionally, the system may include at least one switching unit controlled by the power management controller. The switching unit(s) control an amount of power routed to imaging system components.

Intelligent power management control system and method

A completely self-contained and portable alarm system that senses a condition in which a refrigerator or freezer door is not fully closed using a plurality of spring-tempered metallic sensor switches and which provides an audible tone from a piezoelectric transducer. By means of a selector switch, the alarm can occur either immediately upon opening the appliance door, after a predetermined delay has expired, or the alarm can be disabled by removing power from the electronic circuit. Compared to other refrigeration alarm systems this invention is not integral to the appliance itself; it senses only door-ajar conditions; is powered by common direct current means; and its mounting location is highly flexible. It can be easily installed by magnetic means on either side, or top of the appliance near the door by simply placing it where desired, accommodating a large number of new as well as older appliance models. Since this invention does not depend on sensing a temperature change within the appliance, the audible door-ajar warning can be given before internal temperatures change substantially, allowing the undesirable condition to be remedied much earlier than would be the case if temperature sensing were done, thus helping to prevent loss of perishables and to save energy.

Portable refrigeration door open alarm apparatus

A quad-state input signal decoder 100 that decodes conventional three-state signals plus a fourth state in which the input signal 40 is at the frequency of, and synchronized with, a decode clock signal 35 in the decoder. Compared to three-state techniques, this invention achieves a one-third increase in the number of exclusively-active signals that can be communicated through a single line such as a I/O pin 41 of an integrated circuit 110.
