Abstract: A hot food holding station is a device that can keep food warm, especially food that has been deep fried or cooked, thereby providing consumers convenience of serving heated ready-to-eat food. The device further ensures that edibles that are being held are evenly heated across the storage unit. In order to accomplish this, the device uses a heated airflow system that includes multiple air flow passages and a multi-functional grease tray ramp. The heated airflow system includes an air blower unit, an airflow unit, a heated air chamber and a food holding compartment that are fluidly communicated with one another. Further, the device utilizes fresh air from the atmosphere for heating the food, thereby preventing recirculation of air within the system.

Abstract: An ergonomic cooktop scraping utensil has a planar body, a first side support, a second side support, a blade, and a handle. The blade is removably attached to a distal end of the planar body, and the handle is laterally connected between the upper ends of the first and second side supports. When force is applied to the handle, it is transmitted to the side supports and into both the proximal and distal ends of the utensil. The blade is configured to be oriented at a specified blade angle relative to the cooktop surface for efficient scraping action. The handle is designed to be operated by the heel of the palm of the user in order to minimize any moment arm, and thus strain, applied to the wrist of the user.

Abstract: A combination refrigerator-freezer with dividing air-impermeable air-to-air heat exchanger is a system for cooling a refrigerator compartment and a freezer compartment utilizing a single cooling system and without mixing or exchanging air between the refrigerator compartment and the freezer compartment. Cold air is generated by the cooling system and circulated into the freezer compartment and into a freezer airflow compartment where the cold air cools an air-to-air heat exchanger. Warmer air circulating through a refrigerator airflow compartment positioned opposite to the freezer airflow compartment is cooled by the air-to-air heat exchanger and is in turn able to cool the refrigerator compartment. A control unit is utilized to control the temperatures within the refrigerator compartment and the cooling compartment and to ensure that the system is not active while defrosting is in progress. A first defroster and a second defroster are utilized to prevent key components from icing up.

Abstract: The outdoor multi-channel antenna mainly contains a case, a reflection box, a reception plate, and a cover. The reflection box is placed inside the case. The reception plate has an antenna waveguide element and is placed inside the reflection box. The waveguide element is fixed and positioned by a support seat. The reception plate contains a curved piece and two wing pieces bended 90 degrees downward from the curved piece. The waveguide element is attached to a back side of the reception plate and is connected via a coaxial cable to a terminal threading through the through openings of the reflection box and the case. The cover tightly seals the case by a ring washer sandwiched therebetween and a waterproof plug sleeves over the terminal.

Abstract: A multi-directional panel antenna is provided for the reception of TV broadcast VHF and UHF signals. The panel antenna's circuit board has its current path substantially covers the surface of the circuit board so as to produce multi-directional reception patterns. An iron-core winding is configured at a feed-in terminal of the panel antenna for impedance matching and signal concentration. The panel antenna also uses air to reduce dielectric loss. A MMIC signal amplification device is provided for enhanced gain. Ceramic capacitors are provided to increase the reception wavelength of the panel antenna so that it falls within a lower section of the VHF band.

Abstract: An antenna device includes an enclosure defining a receiving compartment and having a back forming a mounting seat for mounting to a fixture and an end forming a connector for connection with a coaxial cable. A reflection case, which is received in the enclosure, includes reflection plates set around the case and has a bottom stamped to form partially cut tabs that are bent upward by an angle of approximately 90 degrees. The diamond-shaped antenna is composed of two quadrilateral antenna boards received in the reflection case and fixed to the bent tabs and has a central portion to which a waveguide is coupled for connection with the connector of the enclosure through a coaxial cable. The enclosure is closed by a cover plate to protect the diamond-shaped antenna from direct exposure to severe weather.

Abstract: The planar multi-directional antenna mainly contains a flat casing and a double-layered circuit board housed inside the casing. The circuit board's two major sides are patterned in a symmetrical manner and traces are routed and extended along the circumference of the circuit board for producing multi-directional reception field pattern. A raised metallic plate is configured in the center on a first major side for avoiding the coupling effect from current converging in the center and for overcoming the dielectric loss by using air. A ferrite core is configured at the feeding terminal of the antenna as a means of impedance conversion. A SMD inductor and a SMD capacitor are provided on the other major side for increasing the antenna's capability of receiving signals of larger wavelength.
