Patent number: 11488788Abstract: The present invention provides a high output voltage supercapacitor having a cathode including layers of phosphorene, an anode comprising zinc, and an organic-solvent-based electrolyte including zinc. The supercapacitor demonstrates a high anti-self-discharge. The organic electrolyte may include an anhydrous zinc salt, tetraethylammonium tetrafluoroborate, and propylene carbonate (Et4NBF4/PC). The electrochemical stability window of Et4NBF4/PC extends beyond 2.5 V. The supercapacitor can be charged to 2.5 V and possesses high initial discharge voltage. The supercapacitor delivered 130 F g?1 even after more than 9500 cycles at a current density of 0.5 A g?1. More importantly, the supercapacitor exhibits a capacitance retention of 70.16% even after 500 hours self-discharge behavior.Type: GrantFiled: October 15, 2021Date of Patent: November 1, 2022Assignee: City University of Hong KongInventors: Chunyi Zhi, Zhaodong Huang, Xinliang Li, Guojin Liang

Patent number: 7360108Abstract: A multi-link receiving mechanism (MRM) is disclosed comprising a plurality of receivers. Each receiver receives a separate data stream, and all receivers receive the same clock signal. The data streams may arrive at the MRM out of alignment relative to each other (i.e. may have inter-pair skew), and the clock signal need not be aligned with any of the data streams. In response to the clock signal and the data stream, each receiver delays the clock signal by a variable delay to derive a reference signal. This is done to achieve a desired relative alignment between the data stream and the reference signal. Once the reference signal is derived, it is used by the receiver to generate a plurality of latching control signals. These latching control signals are thereafter used by the receiver to latch all of the data units of the data stream. Data from the data stream is thus recovered. Each of the receivers operates in the manner described to recover data from each of the data streams.Type: GrantFiled: December 30, 2004Date of Patent: April 15, 2008Assignee: Pixelworks, Inc.Inventor: Guojin Liang

Patent number: 7050512Abstract: An improved receiver architecture is disclosed comprising a latching mechanism coupled to receive a data stream, and a signal generator for generating latching control signals for controlling the operation of the latching mechanism. The signal generator generates one latching control signal per data period of the data stream, with each latching control signal coinciding approximately with the midpoint of a corresponding data period. The signal generator generates the latching control signals based upon a reference signal, which in one embodiment, coincides approximately with the midpoint of a data period of the data stream. The receiver may further comprise an adjustable delay element and a delay adjustment control. The adjustable delay element receives a clock signal and imposes a variable delay thereon to derive the reference signal used to generate the latching control signals. The magnitude of the variable delay is controlled by the delay adjustment control.Type: GrantFiled: January 8, 2001Date of Patent: May 23, 2006Assignee: Pixelworks, Inc.Inventor: Guojin Liang
