Title: System and method for zero voltage switching in a power converter
Inventor: BARON-TROCELLIER NATAN
IPC: H02M7/5387
Filed: 2021-05-18
Granted: 2022-05-31
Abstract: Disclosed is a system for zero voltage switching in a power converter (102, 302) comprising first half-bridge (106, 202) and second half-bridge (108, 204, 310, 312, 314). The first half-bridge comprises first set of transistors (202a, 202b, 304a, 304b, 306a, 306b, 308a, 308b) and output inductor (212). The second half-bridge comprises second set of transistors (204a and 204b) and auxiliary inductor (206). A current sensing means measures (110), at switching cycle scale, average and maximum current values of output inductor and average, minimum and maximum current values of auxiliary inductor. A voltage sensing means (112) measures input and output voltages of first and second half-bridge. A controller (114) is configured to compute dead times of pulse width modulation control signal of second half-bridge, generate pulse width modulation control signal of second half-bridge (108, 204, 310, 312, 314) and to adapt dead times of first half-bridge (106, 202).
Patent HK-1042764-B (HK)
Title: Disc-shaped recording media
Inventor: TORU OKAZAKI
IPC: H04L25/49
Filed: 2002-03-08
Abstract: In the present invention, a partly duplexed conversion table is used as a conversion table for converting an M-bit based data string directly into an N-bit based code string without using margin bits. This conversion table is constituted by first and second sub-tables including plural code groups, respectively. The plural code groups include different codes for the same input data. The second sub-table is a table which is partly duplexed with the first sub-table and is produced by allocating different codes to data from first input data to second input data in the first sub-table. The first and second sub-tables are so designed that code sets of the duplexed portions take variants of digital sum variations which are opposite in sign. Codes are allocated to all the code groups in the duplexed portions of the first and second sub-tables with respect to input data sequentially from a code having a maximum absolute value of variant of the digital sum variation. Thus, according to the present invention, low frequency components of modulated signals may be restricted properly.

Title: Autonomous liquid dosing system
Filed: 2019-10-07
Abstract: A method and a system for fortifying water with an aqueous solution containing one or more minerals or beneficial additives is described. The system provides accurate dosing without the need for an electrical connection.
