Proxy hash table
Some embodiments of the invention provide novel methods for storing data in a hash-addressed memory and retrieving stored data from the hash-addressed memory. In some embodiments, the method receives a search key and a data tuple. The method then uses a first hash function to generate a first hash value from the search key, and then uses this first hash value to identify an address in the hash-addressed memory.

To retrieve data from the hash-addressed memory, the method of some embodiments receives a search key. The method then uses the first hash function to generate a first hash value from the search key, and then uses this first hash value to identify an address in the hash-addressed memory. At the identified address, the hash-addressed memory stores a second hash value and a data tuple. The method retrieves a second hash value from the memory at the identified address, and compares this second hash value with a third hash value that the method generates from the search key by using the second hash function. When the second and third hash values match, the method retrieves the data tuple that the memory stores at the identified address. |

One or more techniques and/or systems are provided for detecting stale data and/or changed data. For example, a bitmap file may be maintained and mapped to an inofile describing various states of files of a file system.

Light emitting device with a light-transmissive member
A light emitting device includes a light emitting element, a light-transmissive member, a covering member, and a base member. The light-transmissive member has a flange on a lateral surface thereof in such a manner as to continue from a periphery of an upper surface to a periphery of a lower surface of the light-transmissive member and to be positioned outside the upper surface of the light-transmissive member and an upper surface of the light emitting element in plan view. The flange has a thin portion at an inner side than the outer edge side of the flange. The thin portion has a thickness smaller than a thickness of the outer edge side of the flange. |

Cooling systems for vehicle headlights
Cooling systems for LED headlight bulbs are disclosed. In some examples, a headlight bulb assembly for a vehicle headlight includes a circuit board and a first light emitting diode (LED) on the first side of the circuit board and a second LED on the second side of the circuit board. The headlight bulb assembly includes a shell at least partially enclosing the circuit board. The shell defines a sealed interior fan housing, an air intake on the first side of the circuit board, and an air exhaust on the second side of the circuit board. A circulator fan in the sealed interior fan housing is configured to draw air into the sealed interior fan housing through the air intake. The circulator fan is configured to expel the air from the sealed interior fan housing through the air exhaust. |

Troffer light fixture
A light fixture with a troffer design. The light fixture includes a housing, LED assembly, and lens assembly. An inner lens can be positioned over the LED assembly to control the distribution of light. A reflector can be positioned over the LED assembly instead of the inner lens to control the light. |

Edge lit fixture
An edge lit fixture. A housing provides the basic shape and structure of the fixture. The housing is constructed from discrete segments including lens frames, side frames, and end frames, which can be used in many different combinations to create the desired fixture. The assembled housing defines an open central area. One or more light panels are arranged around the perimeter of the housing such that at least some of the light is emitted toward the central area. The open central area of the housing allows for existing materials, such as a ceiling tile, for example, to function as a back surface of the fixture. |

Rapid fill compressed gas storage tank
A method for rapidly filling a compressed gas storage tank with a moderated temperature rise using a Coanda nozzle to inject the feed gas into the tank and using the Coanda nozzle to direct the feed gas along the inner surface of the storage tank; entraining the stored gas with the feed gas that is flowing under the influence of the Coanda effect to flow along the inner surface of the gas storage tank; and transferring heat from the flowing gas to the external walls of the tank. Also, a compressed gas storage tank for rapid filling with a moderated temperature rise comprising: a gas storage tank and a Coanda nozzle capable of directing feed gas that is injected into the gas storage tank along the inner surface of the gas storage tank. |

Fiber optic safety system
Safety systems for operating equipment have a source of visible light, a first signal light transmitter, a first signal light receiver, preferably a second signal light transmitter and second signal light receiver. A fiber optic bundle with at least one section of illuminated cable emits the visible light and carries the signal light. The signal light follows an optical circuit through the fiber optic bundle from the signal light transmitters to the signal light receivers. The signal light receivers are connected to suitable controls of the system such that if a predetermined light signal is not received by the signal light receiver(s), the operating equipment will stop and/or alarms will be generated. The fiber optic bundle is connected to optical pull switches which interrupt the light circuit if a person applies a predetermined pull force to the optical fiber bundle. |
