Abstract: A path metric computation method and apparatus for estimating a maximum likelihood sequence in a wireless communication network. The proposed method applies the statistical properties of estimated channel impulse response to reduce the computational load. A threshold is set to check the significance of each autocorrelation value in order to determine the contribution to the path metric increment. The corresponding terms in the path metric equation with insignificant autocorrelation values are thus discarded to reduce the complexity of path metric computation.

Abstract: A method for automated channel updating is provided. In step (a), a frequency carrying channel data is detected. In step (b), it is determined whether a channel list comprises the frequency by retrieving a frequency table, where the frequency table stores information indicating whether the frequency is comprised in the channel list, and the channel list records a mapping relationship between a channel number and the frequency. In step (c), an unused channel number in the channel list is assigned to the detected frequency not in the channel list, where the unused channel number does not map to the frequency.

Abstract: A firmware update method for a data processing device is provided. The data processing device comprises a MBR (master boot record) which targets an OS (operating system) loader of a first OS, and boots the data processing device in the first OS. A virtual disc comprising a loading module, a backup record, and at least one firmware update code is generated, in which the loading module is an OS loader of a second OS. The content of the MBR is stored in the backup record in the virtual disc and the MBR is modified to target a disc address of the virtual disc. The data processing device is rebooted and the MBR is executed to execute the virtual disc targeted by MBR, the data processing device thereby booting in the second OS. The MBR is restored to target the OS loader of the first OS using the backup record in the virtual disc. The firmware update code in the virtual disc is executed. The data processing device is rebooted in the first OS in response to the OS loader targeted by the MBR.

Abstract: A paper tray for use with a printer. The paper tray includes a sidewall, a door plate, a rotating member and a resilient element. The sidewall has a through hole. The door plate pivots on the sidewall and rotates around an X-axis. The rotating member is disposed in the through hole and pivots on the sidewall.

The resilient element is disposed between the rotating member and the sidewall, providing resilience to the rotating member to rotate to the first position. The rotating member rotates to the second position when exerted to overcome the resilience. The rotating member rotates to the first position by the resilience in the absence of external pressure, such that the engagement portion abuts the door plate.

Abstract: The invention provides a water-proof housing for an electronic equipment. The water-proof housing, according to the invention, has built-in drainage to cope with penetration of liquid into the electronic equipment. The water-proof housing essentially includes a main body with a plurality of ventilation holes formed thereon. The housing also includes a plurality of drainpipes which each corresponds to one of the ventilation holes and a collecting hopper is formed at one end thereof. The drainpipes are mounted on an inner wall of the main body such that each of the collecting hoppers is disposed underneath the corresponding ventilation hole. Once liquid flows into the interior of the electronic equipment through the ventilation holes, the liquid is collected by the collecting hoppers and drained out of the electronic equipment from an outlet.

Abstract: An electronic device includes a housing, a lamp having a voltage rating, a ballast electrically connected to the lamp, a main board having a predetermined voltage and electrically connected to the ballast, a first fan electrically connected to the main board, and a second fan electrically connected to the main board. The lamp, the ballast, the main board, the first fan and the second fan are disposed in the housing, and the first fan is nearer the ballast than the second fan. When the voltage rating of the lamp is greater than the predetermined voltage of the main board, the main board actuates the first and second fans to dissipate heat from the lamp and other elements in the housing. When the voltage rating of the lamp is less than the predetermined voltage of the main board, the ballast actuates only the first fan to dissipate heat from the lamp.
