A test circuit first detects whether or not a relay unit is normal, and then examines an operation of leakage detecting circuit. This allows relay unit to interrupt an electric power supply path including power lines more securely if electrical leakage occurs in the electric power supply path. If welding in the contact of the relay unit is detected before starting charging of a power storage device included in an electrical device, a control device does not allow the charging of the power storage device, which can prevent a problem from occurring in the electrical device.

A controller may also be linked to the various components of the fireplace to receive data therefrom and for control thereof. A sensor linked to the control can be placed at a heat outlet in order for the controller to detect temperature and accelerate the ventilator if need be. A bypass is also used to avoid cool air from the air conditioner from heating up when the decorative flame is lit.

Apparatus includes a main body having a function of reducing performance of the apparatus during operation, an AC adapter which is connectable to the main body and supplies power to the main body from a commercial power source, and a rechargeable battery which is connectable to the main body and discharges to supply power to the main body. Apparatus operates without reducing the performance even while the power supplied from the AC adapter is turned off and the power is supplied from the battery during a peak shift period (e.g. mid-day summer where limiting the power supplied by the AC adapter is desirable) in a state where both the AC adapter and the battery are connected to the main body, and thereafter, the power supplied from the AC adapter is turned on and power is supplied to the main body from the AC adapter even during the peak shift period.

Methods and apparatus for managing electrical loads of electronic devices are disclosed. According to one embodiment, a current load imposed by an electronic device, such as a memory device (or memory system), can be measured. Then, using the measured current load, the memory device can determine whether (and to what extent) operational performance should be limited. By limiting operational performance, the memory device is able to limit its current load so as to satisfy a specification criterion or other requirement. The electrical load management is well suited for use in portable memory products (e.g., memory cards) to manage current loads being drawn.

A fuel injector is described that includes a polymeric housing, pole piece, filter assembly, coil assembly, spring member, armature assembly and metering assembly. The housing has a passageway extending between an inlet opening and an outlet opening along a longitudinal axis. The pole piece is disposed in the passageway and has a through opening. The filter assembly has a portion disposed in the through opening of the pole piece. The coil assembly is disposed in the housing to surround the pole piece. The spring member is disposed partly in the pole piece and includes a spring portion contiguous with the portion of the filter assembly. The armature assembly is disposed in the passageway in a first position confronting the end face of the pole piece and in a second position contiguous to an end face of the pole piece. The metering assembly has a seat secured to a polymeric support member. The seat has a first surface contiguous to the closure member in one position of the closure member and a second surface spaced apart from the first surface. The metering disc is secured to the second surface of the seat such that the metering disc is at the outermost end of the fuel injector.

Various methodologies relating to a polymeric fuel injector are disclosed. One method provides for manufacturing the fuel injector by forming a polymeric housing over a coil assembly and electrical connectors to provide a polymeric passage extending from an inlet to an outlet along a longitudinal axis; inserting components into the polymeric passage from at least one of the inlet and outlet; and securing a polymeric support member of a metering assembly to the housing. Another method provides for manufacturing a fuel injector housing by hermetically enclosing a polymeric housing over a coil assembly and electrical connectors to provide a continuous polymeric passage, the polymeric passage directly facing the longitudinal axis. Yet another method provides for manufacturing a metering assembly by providing a seat; and molding at least a portion of the seat to provide a polymeric support member that surrounds the outer circumference of the seat.

A control device for an internal combustion engine provided by the present invention is a control device which can satisfy both a requirement relating to exhaust gas performance of the internal combustion engine and a requirement relating to operation performance by properly regulating a change speed of a required air-fuel ratio, in the internal combustion engine which uses torque and an air-fuel ratio as control variables. The control device receives the requirement relating to the exhaust gas performance of the internal combustion engine, and calculates an air-fuel ratio which satisfies the requirement as a required air-fuel ratio. When a predetermined reduction condition is not satisfied, an original required air-fuel ratio is directly determined as a final required air-fuel ratio. However, when the reduction condition is satisfied, the change speed is reduced by processing the signal of the original required air-fuel ratio, and determines the required air-fuel ratio with the change speed reduced as the final required air-fuel ration. The reduction condition includes a condition that the change amount of the original required air-fuel ratio, in more detail, a change amount per calculation period is larger than a predetermined air-fuel ratio change determination value.

The present invention relates to a broadband wireless access system, and more particularly, to a method of preventing a terminal from performing an unnecessary operation in a multicarrier environment, and a device for performing the method. An operating method of a terminal operating as a carrier aggregation mode in a broadband wireless access system supporting a multi carrier according to an embodiment of the present invention includes: obtaining system information on a neighbor base station and trigger function information applied to a carrier aggregation mode through a first broadcast message broadcasted from a serving base station; scanning a channel state for at least one carrier of a neighbor base station supporting a multicarrier by using the obtained system information; and transmitting a second message to the serving base station if the scanning result satisfies a condition based on the trigger function information.

A system and method for generating indices to quantify operating transition performance of a continuous process, such as a sheet forming process, includes a computer system that is configured to generate a normalized overall transition performance index. The overall transition performance index is formed from a plurality of individual parameter indices associated with specific production components or portions of the process line. As such, the individual parameter indices allow a user of the system to readily identify the particular portion of the continuous process line that is performing below desired levels. In addition, because the overall transition performance index is normalized, it enables comparison of the operating transition performance of multiple process lines.
