Title: Look-through mutagenesis for developing altered polypeptides with enhanced properties
Inventor: CREA ROBERTO
IPC: C07K16/00
Filed: 2005-07-06
Abstract: A method of mutagenesis by which a predetermined amino acid is introduced into each and every position of a selected set of positions in a preselected region (or several different regions) of a polypeptide to produce a library of polypeptide analogs is disclosed. The method is based on the premise that certain amino acids play a crucial role in the structure and function of proteins and thus is capable of identifying and distinguishing functional amino acid residues (“hot spots”) from non-functional amino acids residues (“cold spots”) within a polypeptide or portion thereof. Libraries can be generated which contain only desired polypeptide analogs and are of reasonable size for screening. The libraries can be used to study the role of specific amino acids in polypeptide structure and function and to develop new or improved polypeptides such as antibodies, antibody fragments, single chain antibodies, enzymes, and ligands.
Patent EP-1804440-A4 (EP)
Title: A method and circuit for acquiring an asynchronously de-map clock
Inventor: JI KUIWEN
IPC: H04L12/56
Filed: 2006-03-15
Abstract: A method and a circuit for obtaining asynchronous demapping clock. The method includes: obtaining a smoothed clock with even gaps in accordance with data to be demapped and a corresponding clock signal; performing phase locking in accordance with a signal reflecting writing and reading conditions of data of a First In First Out (FIFO), to obtain a clock signal required for demapping. The method can effectively filter off jittering created during asynchronous mapping/demapping processes and may ensure a high-performance clock output. Furthermore, the method is applicable to not only mapping from OTN to SDH but also other asynchronous demapping processes, e.g., mapping from SDH to OTN, and thereby effectively improving the performance of data demapping.

Abstract: An electronic taximeter having a microcomputor (30) is adapted to store the current calibration factor of the meter and cause, upon initiation, display thereof on an electronic display (54). An electronic revolution counter (47) is adapted to progressively count and display the revolutions of a speedometer cable input to said meter such that calibration may be checked by driving the vehicle over a measured distance. Calibration may be readily altered merely by selecting different combinations of an 8-switch dual-in-line package (44). Other features include a real time digital clock (31) whereby total engaged time of the taxi during any particular period and the time of commencement and conclusion of a particular fare may be computed. Tariff rates may be altered by replacement of a single re-programmable and hence re-usable memory chip (33) and a miniature rechargeable battery (35) continuously trickle charge by the vehicle electrical supply ensures retention of all data including current operation mode data for up to about six months in the event of loss or failure of said supply. This latter feature is made possible by cyclically dumping, about every millisecond, current operation mode data into low power read/write memory circuits, wherein all other data is also stored, and powering said memory circuit by said battery in the event of said loss or failure.

Title: Power supply control for integrated circuit.
Inventor: ASWELL CECIL JAMES
IPC: G11C5/14
Filed: 1981-05-27
Abstract: A power supply control circuit (20) selectively provides power to an integrated circuit from either a primary power supply terminal (22), or through terminals (24, 26) connected to backup batteries. The voltage level of the primary power is monitored continuously and when it drops to a predetermined level one of the two backup batteries is substituted to power the integrated circuit in a power-down mode. The circuit (20) includes a level detector circuit (32) and a voltage reference circuit (98). In the power-down mode one battery is connected to power the integrated circuit and this battery is continuously monitored. When the voltage of the on-line battery drops to below a fixed level in comparison to off-line battery a control logic circuit (92) activates switches (56) to substitute the off-line battery for the on-line battery. Control logic circuitry (92) is provided to disconnect the control signals from the integrated circuit to prevent loss of stored information. Further the failure of one of the backup batteries is indicated by disabling a write enable signal.

Title: Deaeration of ink in an ink jet system.
Inventor: HOISINGTON PAUL A
IPC: B41J2/19
Filed: 1988-03-31
Abstract: In the particular embodiment of an ink deaerator described in the specification, an elongated ink path leading to an ink jet head is formed between two permeable membranes. The membranes are backed by air plenums which contain support members to hold the membranes in position. Reduced pressure is applied to the plenums to extract dissolved air from the ink in the ink path. Increased pressure can also be applied to the plenums to eject ink from the ink jet head for purging. Within the ink jet head ink is circulated convectively from the orifice to the deaerating path even when the jet is not jetting ink.
Patent EP-0389566-A4 (EP)
Title: Improved low power dual-mode cmos bias voltage generator
IPC: G11C16/06
Filed: 1988-12-02
Abstract: A substrate voltage bias generator is disclosed including a charge pump whose output is clamped during charge pump capacitor charging cycles to zero volts thereby eliminating a voltage drop associated with prior art clamping diodes. The charge pump further includes a stand-by and booted mode, the stand-by mode providing a first level of output current at a specified generated substrate bias voltage and in the booted mode generating increased output current and voltage. The increased voltage is generated across the charge pump capacitor by a second capacitor that is only operative in the booted mode and whose charge is shared with the charge pump capacitor thereby developing a higher voltage across the charge pump capacitor. The output voltage generated by the substrate bias generator is detected and if it is too low a voltage, the booted mode is turned off. An external signal determines whether the stand-by mode or booted mode are selected.

Patent EP-0422032-A4 (EP)
Title: Cable televison spread spectrum data transmission apparatus
IPC: H04N7/173
Filed: 1989-04-28
Abstract: Apparatus for transmitting data spread across at least a portion of the bandwidth of a cable television channel comprises a carrier signal oscillator, a frequency divider, a pseudorandom sequence generator and two exclusive OR gates. A first exclusive OR gate serves to spread a data signal across the pseudorandom noise sequence generator having a much higher chip rate than the bit rate of the data signal. The second exclusive OR gate modulates the spread spectrum data signal to a carrier frequency for transmission over the cable television channel. The apparatus may be applied for return path transmission in the 0-30 megahertz band which is high susceptible to interference noise and provides approximately a 20 dB signal to interference ratio advantage over known data coding and transmission schemes. A microprocessor normally present in a cable television terminal may format data for transmission, control the spread spectrum modulation process and control gain control circuitry for introducing an appropriate power level into the cable plant.

Patent EP-0452330-A4 (EP)
Title: Method and apparatus for diagnosing intracellular parasite infections using an enzyme detection system
IPC: C12M1/34
Filed: 1989-10-25
Abstract: The present invention involves a highly specific chemical system for detecting parasite-infected cells. The method is especially effective in detecting intraerythrocytic diseases, especially malaria. With respect to malaria, chemical agents are used to detect enzymes produced by the infecting parasites. Blood samples are combined with a plurality of substrates which are subjected to enzymatic hydrolysis. Hydrolysis is rapid and may be detected in two ways. The first method involves substrates having a fluorescent detecting group. Upon hydrolysis, the fluorescent group is cleaved and detected using a conventional fluorescent light source. Alternatively, substrates may be used having a detecting group which forms a visibly colored material when combined with a secondary reagent. These techniques produce a unique colored or fluorescent pattern which enables the rapid and accurate determination of parasite infection. Furthermore, parasite diagnosis is accomplished without the use of expensive and complex diagnostic equipment.
