Musical instrument

A method and apparatus for latency control in an optical network. A management node such as an OLT in a PON sends a discovery message intending to prompt joining network nodes such as ONUs to send a response on a first wavelength during a quiet window established for this purpose. When a response is received, a secondary upstream-transmission wavelength is assigned to the ONU. When the ONU sends data upstream according to a schedule calculated by the ONT, which schedule may include transmission times using the assigned secondary wavelength. In this case, the assigned secondary wavelength will be scheduled using a relatively smaller or no quiet window. This scheduling may be determined in part by the service or services used by the ONU.

A silo-mountable rescue assembly for accessing a distressed person in a silo includes a tripod that is configured to couple to a top of a silo so that an apex of the tripod is substantially centrally positioned over an opening in the silo. A block and tackle is coupled to the tripod proximate to the apex. The block and tackle is configured to lower equipment and personnel into the silo to rescue a distressed person in the silo.

A composition and method is provided to modify sperm fertility and sex ratio of mammalian offspring. The composition includes an amount of a class of compounds of phenoxazine or phenothiazine, having the structure (see FIG.) and ionic derivatives thereof, wherein R1 is H, a lower alkyl group or N (R3)2, R2 is N, S, O, and R3 is H or a lower alkyl group. A second component of the composition is an amount of an electron transfer agent capable of oxidizing a reduced cofactor (NADPH or NADH). A third component of the composition is an amount of a hexose sugar and/or the phosphorylated esters of such. When mixed with living sperm prior to or at the time of insemination, the composition results in modified rates of conception and an alteration of birth sex ratio.

A composition and method is provided for modifying sperm fertility in mammals for the purpose of biasing the gender in favor of male offspring. The composition includes an amount of a class of compounds of phenoxazine or phenothiazine, having the structure (FIG.) and ionic derivatives thereof, wherein R1 is H, a lower alkyl group or N(R3)2, R2 is N, S, O, and R3 is H or a lower alkyl group. A second component of the composition is an amount of a hexose sugar or the phosphorylated hexose esters of such. When mixed with living sperm prior to or at the time of insemination, the composition results in modified rates of conception and an alteration of the birth sex ratio.

A system, and methods for detecting collisions on multipoint shared optical media, comprising an optical receiver, clock phase detector, clock recovery circuit, and a Passive Optical Network (PON) that transmits optical signals wherein the PON, the clock recovery circuit, and the clock phase detector are communicably coupled to the optical receiver, detecting of the collision is determined by a distortion of transition times of the optical signals at the optical receiver.

A topical, therapeutic composition is disclosed which is useful in relieving inflammatory muscular discomfort in a human being. The composition comprises: at least one of cider vinegar and red vinegar; isopropyl alcohol; and ethyl alcohol which are mixed with bleach flour and corn starch to form a paste which is applied to the human being at an area of inflammatory discomfort. Also disclosed is a method of relieving inflammatory muscular discomfort in a human being comprising the steps of: applying a paste, comprising at least one of cider vinegar and red vinegar; isopropyl alcohol; and ethyl alcohol, mixed with bleach flour and corn starch to form the paste, to the human being at an area of inflammatory discomfort; covering the applied paste with a cloth; loosely wrapping the area of inflammatory discomfort; and allowing the applied paste to remain on the area of inflammatory discomfort overnight.

In a SONET-access product, channel-associated signaling is rearranged into SONET-formatted signaling, with the signaling for added channels being multiplexed with the signaling for through channels, in accordance with a control signal received from a channel map RAM, which stores one bit of data for each channel to indicated whether it is a through channel or an add channel. The RAM is provisioned by a network control processor.

Sonet transmit signaling translator

A synchronous optical transmission system for interfacing SONET formatted channels to lower speed channels in either a SONET format or otherwise. The transmission system incorporates a fiber transmission system, terminal multiplexers and add/drop multiplexers that in turn incorporate a plurality of features, such as parallel scrambling circuitry, frame synchronization circuitry and the like.

Synchronous optical transmission system

The four signaling bits contained in the eight-bit SONET signaling bytes are read from the SONET signaling row and are converted to four parallel signaling bits for storage in a RAM in quasi-SONET format, with sets of four A, four B, four C and four D bits for four consecutive channels being stored for an even and an odd tributary in one RAM memory row. Storing sets of four of the same bit for four consecutive channels simplifies the RAM write operation. A read-modify-write system is used for updating the RAM storage, wherein a row of RAM is read, modified by eight new signaling bits from two consecutive SONET signaling bytes, and is rewritten into the RAM. New signaling bits are stored to accumulate eight new signaling bits for two tributaries prior to updating the RAM with the new bits for both tributaries. The 32 signaling bits output during a RAM read operation are selectively multiplexed to output only four bits associated with a particular channel.

Sonet receive signaling translator

A system for aligning framing bits from independent digital transmission facilities with framing of a higher transmission rate facility includes a RAM memory. Received framing bits from the independent digital transmission facilities are stored at RAM locations in accordance with multiframe addresses of the framing bits relative to the multiframe format of the independent facility. Multiframe indicator bytes indicative of the framing of the higher transmission rate facility are used as addresses to read framing bits from RAM. The multiframe address of the independent digital transmission facilities is established by a counter for each independent facility, said counter being synchronized to the framing of the independent facility and incremented to provide addresses identical to the multiframe indicator bytes of the higher transmission rate facility.

System for aligning transmission facility framing bits to the sonet H4

A filtering algorithm for the SONET H4 byte is implemented with circuitry including an internal H4 counter which is incremented each frame and is locked to a received H4 byte once every 24 frames if a proper bit sequence is detected in a designated frame. If the designated bit sequence is not detected, the counter is not reset and continues to be incremented. If parity errors are detected, the counter is not reset and is allowed to free run to simulate the appropriate H4 byte input.

SONET 4h byte receiver and filter

An H4 byte generating algorithm is implemented by circuitry which includes counters for generating the H4 byte. The circuit is provisioned to indicate whether it is operating in a terminal multiplexer mode or an add-drop multiplexer mode. In the terminal multiplexer mode the counters are allowed to free run and continually produce successive H4 byte outputs. In the add-drop multiplexer mode selected counter outputs are compared with the received H4 byte and the number of mismatches is accumulated by a mismatch counter. When the mismatch counter reaches a predetermined number the value of the received H4 byte is loaded into the H4 byte counters and the mismatch counter is reset. Each time a proper match between H4 counter outputs and the received H4 byte is sensed, the mismatch counter is reset to 0. The presence of a red alarm will also result in the resetting of the mismatch counter and free running of the H4 byte counters.
