An LED lamp including a light guide/light pipe, and a method of reflecting light using same, are disclosed. The LED lamp includes a transparent light pipe enclosed in an envelope, where the light pipe has a lower section and an upper section. The lamp also includes an LED in a recess at a lower end of the lower section, and a reflector formed by an indentation in an upper end of the upper section. The lower section may be a compound parabolic concentrator, and the upper section may be a tapered cylinder. The lower section of the light pipe collects light emitted from the LED, the upper section of the light pipe directs the collected light onto the reflector, and the reflector reflects the directed light in a radial direction.

The present invention relates to a reversible backwashing self-cleaning filter, including a filter mechanism, a backwashing drive mechanism driving a sewage suction assembly, and a high-pressure washing apparatus. The high-pressure washing apparatus includes a high-pressure washing pump and at least one high-pressure branch pipe arranged along the outer wall of the fine strainer and operating synchronously with the sewage suction assembly, where a plurality of spray nozzles are spacedly arranged where the high-pressure branch pipe is opposite to the outer wall of the fine strainer. With collaboration of translation and rotation of the sewage suction assembly, the inner and outer walls of the entire fine strainer are thoroughly cleaned, suitable for real-time purification of a low-pressure water circulating system.

The present invention provides a self-cleaning suction filter including a filter mechanism and a sewage suction assembly. The sewage suction assembly is rotatably arranged at the center of a fine strainer and communicated with a sewage discharge cavity through a sewage suction pipe, and the sewage suction pipe is spacedly and fixedly provided with a plurality of “T”-shape suction nozzles for suctioning deposits on the inner wall of the fine strainer. The self-cleaning suction filter further includes: a sand collection cavity arranged at the tail of the fine filter cavity and communicated with the fine filter cavity; and the coarse filter cavity, the fine filter cavity, and the sand collection cavity descend in height. Water are automatically collected in the sand collection cavity and discharged in time, thereby ensuring the stable filter function after the filter is used for a long time.

An over-the-air (OTA) bootstrap method and system are described, including: when a connection between a user-registered terminal device and a device management (DM) server is finished, the terminal device sends a bootstrap confirmation message to a service center corresponding to port information of a valid service center pre-stored in the terminal device; the service center analyzes the bootstrap confirmation message to determine a device ID of the terminal device, connects with a DM server authorized by the service center, and searches for an OTA bootstrap record corresponding to the device ID in a database of the authorized DM server; if the service center fails to find the corresponding OTA bootstrap record in the database of the authorized DM server, the service center notifies the user that the terminal device has performed an OTA bootstrap with an unauthorized DM server. The present invention can improve the security of the OTA bootstrap.

The present invention relates to compositions and methods comprising genes and peptides associated with cyclic peptides and cyclic peptide production in mushrooms. In particular, the present invention relates to using genes and proteins from Galerina species encoding peptides specifically relating to amatoxins in addition to proteins involved with processing cyclic peptide toxins. In a preferred embodiment, the present invention also relates to methods for making small peptides and small cyclic peptides including peptides similar to amanitin. Further, the present inventions relate to providing kits for making small peptides.

A mechanical interface for a glass bulb is provided. The mechanical interface includes a connector and an optical mount. The connector is in contact with the glass bulb. The connector may be a separate component attached to the glass bulb, or may be a continuous part of the glass bulb, such that the connector is itself made of glass. The optical mount is configured to receive the connector. In so receiving, the optical mount operatively couples with the connector so as to secure the glass bulb in a position. The optical mount is also configured to attach to a lamp housing. A solid state light source retrofit lamp may thus be formed of a lamp housing including a solid state light source light engine and its required components, a glass bulb, and a mechanical interface for the glass bulb.

A rear-loading LED module for a rear combination lamp is disclosed. One or more LEDs are mounted on a printed circuit board that electrically powers and mechanically holds them outside a faceted, parabolic reflector. Light emitted from the LEDs enters a light propagation region, formed between the reflective adjacent faces of two nested cylinders. The cylinders extend from the LEDs, outside the reflector, longitudinally through a hole at the vertex of the reflector, to the focus of the reflector. In some applications, the light propagation region may act as a beam homogenizer, so that light exiting the light propagation region may have roughly uniform intensity. Light from the light propagation region strikes an outwardly-flared reflector that directs it largely transversely onto the parabolic reflector. The parabolic reflector collimates the light and directs it longitudinally, through a transparent cover and out of the lamp. The parabolic reflector may have facets that angularly divert portions of the reflected light to form a desired two-dimensional angular distribution for the exiting beam.

A wide-locking range phase locked loop circuit includes a decision unit and a closed loop connection comprising a phase frequency detector, a charge pump, a loop filter, a voltage controlled oscillator, and a multi-modulus divider. The decision unit receives a phase difference signal outputted from phase frequency detector and the control voltage outputted from the loop filter and determines to select a specific divisor form the plurality of divisors provided by the multi-modulus divider if the phase difference signal indicates an unlocked state and the control voltage is not within a standard voltage operation range.
