If the data of a large number of pages of a block are to be updated, however, the updated pages are written into an unused erased block and the unchanged pages are also written to the same unused block. By handling the updating of a few pages differently, memory performance is improved when small updates are being made.

Systems and methods for packet re-transmission in multi-hop wireless networks are provided. RLP packet retransmission only starts from the hop where L1 ARQ fails. This may result in an increased efficiency of radio resource utilization. In particular, the benefit may be greatest for implementations where the last hop is more unstable than the remaining hops. This is the case for the cellular downlink where the last hop is between a relay and a mobile terminal, and this hop is typically the most unstable. However, applications are not limited to this particular case. Any improvement in RLP recovery delay may be translated into an improvement in system capacity and per-terminal throughput.

The received lighting profile is then deviated from, in response to the received input, by increasing the intensity of the light to illuminate at a second intensity for a predetermined period of time. A message is transmitted for receipt by the control center, the message including an indication of the increased light intensity and an identifier associated with the first lighting assembly.

Various apparatuses and methods for replacing a fluorescent lamp with a non-fluorescent tube are disclosed herein. For example, some embodiments provide an apparatus for replacing a fluorescent lamp, including an electrical connector adapted to electrically connect to a fluorescent lamp fixture, a DC rectifier connected to the electrical connector, a voltage converter connected to the DC rectifier, and a non-fluorescent light source connected to the voltage converter. The DC rectifier, voltage converter and non-fluorescent light source are substantially contained within a housing that is physically configured to replace the fluorescent lamp in a fluorescent lamp fixture.

With respect to a vacuum tube having a reduced pressure vessel containing an electric discharge gas sealed therein, problems such as the lowering of discharge efficiency owing to an organic material, moisture or oxygen remaining in the reduced pressure vessel have taken place conventionally. It has been now found that the selection of the number of water molecules, the number of molecules of an organic gas and the number of oxygen molecules remaining in the reduced pressure vessel, in a relation with the number of molecules of a gas contributing the electric discharge allows the reduction of the adverse effect by the above-mentioned remaining gas. Specifically, the selection of the number of molecules of the above electric discharge gas being about ten times that of the above-mentioned remaining gas or more can reduce the adverse effect by the above-mentioned remaining gas.

A light emitting device includes a light emitting element that emits primary light and a wavelength conversion unit that absorbs part of the primary light and emits secondary light. In the light emitting device, the wavelength conversion unit includes a plurality of types of phosphors that emit secondary light having wavelengths different from each other, and at least one of the phosphors is a covered phosphor covered with a surface film that reflects secondary light emitted from a phosphor other than the covered phosphor.
