Inventors:

Walter Evanyk - Plano TX 75074

International Classification:

A45D 2000

US Classification:

34 96, 34 97, 392384, 392385

Abstract:

The present invention relates to a blower dryer appliance typically used for drying and styling hair. When electrically activated, these appliances virtually always route electrical power to the fan or blower motor prior to or simultaneously with the heating element(s). Semiconducting switching devices used for regulating, controlling and/or switching electrical power generate waste heat that must be dissipated. Typically, heat is conducted and/or channeled away from the semiconducting switching device through a heat sink which is thermodynamic-mechanically coupled to the device. The greater the coverage area of the heat sink, the more waste heat can be dissipated depending on the ability of the heat sink to make contact with cooler, ambient air. This adds costs to the dryer/blower for engineering the heat sink, cost of the sink itself, and necessary design changes in the dryer/blower for accommodating the sink. The presently disclosed invention utilizes the inherent characteristics of the dryer/blower for channeling and reusing waste heat generated from an active switching device by positioning the active device in the air path of the blower.

International Classification:

H05B003/00
H05B001/02

US Classification:

219240, 219492, 2221465

Abstract:

The present invention relates to a portable adhesive dispensing appliance with adjustable duty cycle. Rather than applying power continuously to the heating element, the element power is intermittently switched over to a variable duty cycle. Savings are gained in three areas: extended life of the element; less heat lost to thermal radiation; and less adhesive waste due to dripping and overheating. The duty cycle may be adjusted manually or automatically based on the temperature of the adhesive in the melt chamber. Additionally, the voltage and/or current to the heating element may be adjusted, either manually or automatically, for more rapid recovery during high usage periods. Higher throughput is achieved by sensing the temperature, comparing the temperature to a desired temperature, and then increasing the duty cycle by either or both one of increasing the frequency of duty pulses and/or lengthening the duration of the duty pulses.

Abstract:

The present invention relates to a solder heating appliance with variable duty cycle. Rather than applying power continuously to the heating element, the element power is intermittently switched over to a variable duty cycle. Savings are gained in three areas: extended life of the element; less heat lost to thermal radiation; and less solder waste due to dripping and overheating. The variable duty cycle may be adjusted manually or automatically based on the temperature of the heating element, or tip. Additionally, the voltage and/or current to the heating element may be adjusted, either manually or automatically, for more rapid recovery during high usage periods. Higher throughput is achieved by sensing the temperature, comparing the temperature to a desired temperature, and then increasing the variable duty cycle by either or both one of increasing the frequency of duty pulses and/or lengthening the duration of the variable duty cycle.

International Classification:

A61B005/00

US Classification:

600/300000, 128/903000

Abstract:

A system for wirelessly monitoring, in real time, certain physiological/biological parameters of an animate body, such as an athlete or a patient. The parameters are sensed and measured by a transducer located on the animate body. The transducer is part of a transponder that includes an electronic unit containing a wireless receiver/transmitter. Remote R/T access units are spaced such that at any given time, signals from the transponder will be received by at least one of the access units where the data can be coupled to a display monitor and the measured parameters viewed in real time. In addition, a real time video image of an animate body, such as a patient/athlete, may be transmitted to a remotely located monitor for monitoring along with the transmitted physiological/biological patient parameters.

US Classification:

034096000, 034091000

Abstract:

An improved method and apparatus for improving hair management devices, preferably portable devices, such as curling irons and hot air brushes by including novel heating elements and circuits. A novel elongated heat transfer hollow tube is formed of a metal that is preferable perforated with small holes and that heats and cools quickly such as copper, aluminum, or brass. The hollow tube has sufficient wall thickness for rigidity but is sufficiently thin to allow rapid heating and cooling. In addition, a novel heat source is formed with a light bulb, preferably halogen, located with said hollow tube that likewise heats and cools quickly. The light bulb is removable and replaceable in case of damage. A unique circuit automatically applies full power to the unit until it reaches the desired temperature and then allows a control circuit to automatically reduce the power applied to a value sufficient only to maintain the desired temperature. In the preferred embodiment, a bimetallic switch is coupled in parallel with the control circuit to allow full power to be applied to the heating source to obtain rapid heating of the hollow tube and then allows the control circuit to automatically reduce the power to an amount sufficient only to maintain the desired temperature of the hollow tube.

Abstract:

An improved circuit for automatically controlling energy to electrical energy consuming devices according to the well-known equation   () where P=Power output, P=Power input, P=Power losses, and P=Residual Power. Thus, the invention relates to a method and apparatus for obtaining a desired output power, P, from an electrical load by supplying sufficient pulse time modulation energy, P, to the device to replace only losses, P, and to maintain only the residual power, P, thus maintaining the desired Power output, P, and thereby conserving input energy, Pi, that would otherwise be wasted.
