Patent number: 9313291Abstract: A communication channel in a network maintains client-server transparency while providing reduced bandwidth in the channel. A first and second node can communicate a compressed form of the object data between themselves in the channel. One of the first or second nodes hosts a cache database that can store, transparently to the client, the requested object data. The stored object data can be used to decompress the compressed object data communicated between the first and second node. One of the nodes can provide control signals to the other node to indicate whether the requested object data is stored in the cache database. This configuration preserves transparency between the client and the server while permitting reduced bandwidth usage between the first and second nodes via the compressed object data.Type: GrantFiled: March 14, 2013Date of Patent: April 12, 2016Assignee: Dialogic CorporationInventors: Benny Lavi, Tal Inbar, Ehud Bart, Oded Katz

Patent number: 8629708Abstract: A frequency quadrupler comprises a balanced topology which increases broadband odd harmonic suppression. The frequency quadrupler is constructed in a cascode configuration which is a two-stage amplifier composed of a transconductance amplifier followed by a current buffer. The cascode is constructed with common emitter (CE) and common base (CB) stages which further improves the multiplier frequency response. The cascode configuration enables a notch filter to be placed between the common emitter and common base stages to reduce 2nd harmonic generation and thereby increase 4th harmonic output power, generation efficiency and conversion gain. To cancel 4th harmonic components at the input that may destructively interfere with the output signal, capacitors are placed at the input of the common emitter stage, which in conjunction with the parasitic base wire inductance, form a notch filter to short the 4th harmonic.Type: GrantFiled: January 22, 2012Date of Patent: January 14, 2014Assignee: International Business Machines CorporationInventors: Roee Ben-Yishay, Roi Carmon, Danny Elad, Oded Katz, Benny Sheinman

Patent number: 8381161Abstract: A computer-implemented method identifies at least one proprietary geometric figure from a plurality of geometric figures within a design data layout format file. The proprietary geometric figure in the design data layout format file may be replaced with a placeholder geometric figure. Cell names and connection names associated with the proprietary geometric figure are renamed from a netlist file that defines electrical connections between the geometric figures with obfuscating names. A modified design data layout format file may be generated that includes the placeholder geometric figure and a modified netlist file including the obfuscating names. The modified file enables IC designers to complete their design and checking activities, but inhibits reverse-engineering of the proprietary geometric & netlist data.Type: GrantFiled: November 4, 2011Date of Patent: February 19, 2013Assignee: International Business Machines CorporationInventors: William R.

Patent number: 7994846Abstract: A feedback mechanism to reduce current variation observed in a current reference branch circuit by using body voltage control to compensate process, temperature and supply voltage variations. The current reference output voltage, which is proportional to the reference current, is sampled into a feedback loop, which controls the field effect transistor body voltage.
