A method for measuring degree of packet congestion on a channel of a packet communication network. The method includes: during a training mode, generating an mathematical relationship between the degree of packet congestion on the channel and a plurality of measurable features of the network over a plurality of network conditions; and, during a subsequent normal operating mode, periodically measuring the plurality of measurable features and applying the generated mathematical relationship to such periodically measured plurality of measurable features to determine actual degree of congestion on the channel; and comparing the actual degree of congestion on the channel with a predetermined channel congestion threshold level. The degree of packet congestion on the channel is saturation level. The measurable features include: time delay between transmission starts and terminations of the previously transmitted packet; the fraction of time the channel is busy; and, average number of packet transmission retries.

An automated materials handling system comprises a plurality of overhead hoist buffers (OHBs) for receiving a plurality of semiconductor wafer carriers. Each OHB is assigned to a respective one of a plurality of categories. Each wafer carrier is associated with one or more of the plurality of categories. Each respective category is associated with at least one of a plurality of event trigger types. An overhead transport (OHT) if provided for transporting each of the plurality of wafer carriers to a respective one of the OHBs in response to a respective trigger event. Each trigger event has one of the plurality of event trigger types. Each wafer carrier is stored in a respective one of the plurality of OHBs assigned to a respective one of the categories associated with the respective event trigger type of the trigger event causing that wafer carrier to be transported and stored.

A solid state drive and a method for constructing a logical-to-physical table of the solid state drive are provided. Once the solid state drive is powered on again, the logical-to-physical table and the bitmap table are directly read from the flash memory. Then, the blocks whose history numbers are higher than the reference history number are searched from the flash memory. According to the history numbers in an ascending order, the physical-to-logical data in the blocks are sequentially reconstructed into the logical-to-physical table and the bitmap table of the mapping unit. Consequently, the logical-to-physical table and the bitmap table can be quickly reconstructed.

A solid state drive includes a plurality of dies. The dies are divided into first-portion dies and second-portion dies. The first-portion dies are located at a user area. The second-portion dies are located at a reserved area. The solid state drive is in communication with a host. The data storing method of the solid state drive includes the following steps. Firstly, if the host generates a plurality of write data to the solid state drive, the plurality of write data are stored into the reserved area. If there is not accessing action between the host and the solid state drive and if the write data are in the reserved area, the write data are stored into the user area. Afterwards, error correction codes corresponding to the write data in the user area are calculated and stored into the reserved area.

A method of patterning a metal alloy material layer having hafnium and molybdenum. The method includes forming a patterned mask layer on a metal alloy material layer having hafnium and molybdenum on a substrate. The patterned mask layer is used as a mask and an etching process is performed using an etchant on the metal alloy material layer having hafnium and molybdenum so as to form a metal alloy layer having hafnium and molybdenum. The etchant includes at least nitric acid, hydrofluoric acid and sulfuric acid. The patterned mask layer is removed.

The invention discloses a light-guiding plate and a manufacturing method thereof. The light-guiding plate includes a light-guiding substrate, a first shielding layer, and a second shielding layer. The light-guiding substrate has a first surface and a second surface opposite to the first surface. The first shielding layer is disposed on the first surface and includes a first light-transmitting portion. The second shielding layer is disposed on the second surface and includes a second light-transmitting portion. Thereby, light emitted from a light source could pass through the first light-transmitting portion, the light-guiding substrate, and the second light-transmitting portion, so that a light-halo phenomenon does not occur on the light-guiding plate.
