Abstract: A method and system of reading data from a storage device. The storage device includes a plurality of physical storage extents. One or more of the storage extents is/are associated with a “void extent” indicator, a void extent being an extent that was the target of an unsuccessful write completion. In one technique a request is received to read the data from the storage device. The physical storage extent(s) on which the requested data is stored is located. If one of the located storage extents has an associated void extent indicator then a read error is returned. In a further technique, a request is received to read the data from the storage device. The physical storage extent(s) on which the requested data is stored is located. The data from the located storage extent(s) is retrieved if the read request is a diagnostic read and if the or one of the located storage extents has an associated void extent indicator.

Abstract: A method, computer program, and computer system are disclosed for managing data corruption identified by an application in a storage subsystem. Data requested of the application by a process is copied from a primary storage device in the storage subsystem to a memory. A data integrity check is performed on the data stored in the memory. If the data integrity check succeeds, the data is provided from the application to the process.

Abstract: A hand-held music-creation device has a plurality of stored samples of sound. The device has an interface comprising a grid, where the rows represent channels in which samples may be selected and the columns represent loop measures. The device allows the user to select which samples are to be played in a given loop measure. A loop is created by assigning samples to available loop measures. The user may hear the resulting composition, comprising a loop repeating indefinitely. Each device may be connected to at least one other device to form a system. The system allows the creation of a longer loop and/or allows an increase in sample selection for each loop measure in the loop.

Abstract: A frequency converter is tested. Labels for a plurality of mixing products are displayed. In response to a user selecting a first mixing product from the plurality of mixing products, appropriate frequencies for the first mixing product are calculated. Also, a measurement configuration for the first mixing product is determined.

Abstract: A motion sensor system is provided that has several sensor units. Each sensor unit is freely movable, easily hidden and includes a motion sensor and a wireless radio frequency (RF) transmitter. The motion sensor system further includes a receiver unit, which includes a wireless radio frequency receiver and a device for communicating receipt of a signal to the user. When at least one of the motion sensors of at least one of the sensor units detects motion, the wireless radio frequency transmitter transmits a signal to the radio frequency receiver of the receiver unit. The receiver unit then communicates receipt of the signal to the user.
