Systems and methods are provided for caching media data to thereby enhance media data read and / or write functionality and performance. A multimedia apparatus, comprises a cache buffer configured to be coupled to a storage device, wherein the cache buffer stores multimedia data, including video and audio data, read from the storage device. A cache manager coupled to the cache buffer, wherein the cache buffer is configured to cause the storage device to enter into a reduced power consumption mode when the amount of data stored in the cache buffer reaches a first level.

A method and instrument to irradiate a light adjustable lens, for example, inside a human eye, with an appropriate amount of radiation in an appropriate intensity pattern by first measuring aberrations in the optical system containing the lens; aligning a source of the modifying radiation so as to impinge the radiation onto the lens in a pattern that will null the aberrations. The quantity of the impinging radiation is controlled by controlling the intensity and duration of the irradiation. The pattern is controlled and monitored while the lens is irradiated.

The method, terminal and computer program product determine the acceleration of a mobile terminal associated with the short-range communication transceiver and adjusts the power consumption of the short-range communication transceiver based upon whether a predefined acceleration threshold has been exceeded. To adjust the power consumption, the frequency at which the transceiver is activated may be altered. Thus, the power consumption of the transceiver may be reduced when the acceleration threshold is exceeded and / or may be increased when the acceleration threshold is not exceeded. Due to the adjustment of power consumption by transceivers, power is conserved in the mobile terminals associated with transceivers, which permits the mobile terminals and the transceivers to operate longer without requiring charging or replacement of the power supply.

A selective nerve stimulation patch includes a substrate having a top surface and a bottom surface, integrated components overlying the top surface of the substrate and being electrically interconnected with one another for generating at least one nerve stimulating signal, electrodes integrated into the substrate and exposed at the bottom surface thereof for applying the at least one nerve stimulating signal to a target nerve, a waterproof, breathable cover overlying the substrate and the integrated components, and a support flange surrounding the substrate and coupling the cover and the substrate together. The support flange has a top surface that slopes downwardly toward an outer perimeter thereof, and at least a portion of the cover conforms to the sloping top surface of the support flange. In one embodiment, the patch generates a high frequency waveform with properties such as amplitude, frequency and the like chosen so as to overcome tissue impedance and the stimulation threshold of the target nerve. The modulated waveform is the waveform obtained by modulating the carrier waveform by a pulse envelope.

A sand control screen assembly (40) is operably positionable within a wellbore (48). The sand control screen assembly (40) includes a base pipe (42) having at least one opening (60) and an internal flow path (44). A swellable material layer (46) is disposed exteriorly of the base pipe (42). A fluid collection subassembly (50) is disposed exteriorly of the swellable material layer (46). The fluid collection subassembly (50) is in fluid communication with the internal flow path (44). A filter medium (62) is operably associated with the sand control screen assembly (40) and is disposed in a fluid path between the exterior of the sand control screen assembly (40) and the internal flow path (44). In response to contact with an activating fluid, radial expansion of the swellable material layer (46) causes at least a portion of the fluid collection subassembly (50) to contact the wellbore (48).

An ebullated bed hydroprocessing system, and also a method for upgrading a pre-existing ebullated bed hydroprocessing system, involves introducing a colloidal or molecular catalyst, or a precursor composition capable of forming the colloidal or molecular catalyst, into an ebullated bed reactor. The colloidal or molecular catalyst is formed by intimately mixing a catalyst precursor composition into a heavy oil feedstock and raising the temperature of the feedstock to above the decomposition temperature of the precursor composition to form the colloidal or molecular catalyst in situ. The improved ebullated bed hydroprocessing system includes at least one ebullated bed reactor that employs both a porous supported catalyst and the colloidal or molecular catalyst to catalyze hydroprocessing reactions involving the feedstock and hydrogen. The colloidal or molecular catalyst provides catalyst in what would otherwise constitute catalyst free zones within the ebullated bed hydroprocessing system. Asphaltene or other hydrocarbon molecules too large to diffuse into the pores of the supported catalyst can be upgraded by the colloidal or molecular catalyst. A slurry phase reactor may be positioned upstream from one or more ebullated bed reactors or converted from a pre-existing ebullated bed reactor.

The method, terminal and computer program product determine the context of the mobile terminal associated with the RFID reader and adjusts the power consumption of the RFID reader based upon the determined context relative to at least one previous context determination. To adjust the power consumption, the frequency at which the RFID reader is actuated may be altered. Thus, the power consumption of the RFID reader may be reduced when no change in the context of the mobile terminal is determined and / or may be increased when a change in the context of the mobile terminal is determined. Due to the adjustment of power consumption by RFID readers, power is conserved in the mobile terminals associated with RFID readers, which permits the mobile terminals and RFID readers to operate longer without requiring charging or replacement of the power supply.
