Patent number: 11683819Abstract: Dynamic configuration of multiple radios of an access point is described. An example of an access point includes a processor; a memory; hardware filters; and a first set of radio chains and antennas, the access point including a first radio mode for operation as a single radio on a first channel to service a first BSS and a second radio mode for operation as a first radio on the first channel and a second radio on a second channel to perform an additional service, wherein the access point is to provide dynamic configuration of the radios including, upon determining that operation of the first channel to service the first BSS is not compatible with a particular hardware filter of the first radio, migrating the first BSS from the first radio to the second radio to service on the second channel, and providing the additional service on the first channel.Type: GrantFiled: June 2, 2020Date of Patent: June 20, 2023Assignee: Hewlett Packard Enterprise Development LPInventors: Nitin Changlani, Farhan Hasnain, Mohd Shahnawaz Siraj, Manoj Thawani, Deven Patel

Publication number: 20230179449Abstract: Systems and techniques are described that are directed to filter frequency response shift compensation, including compensating for shifting in the rejection band of the filter. Compensation for the shifting in the rejection band can include applying a pre-distortion to attenuate edge resource units (RUs), and applying PHY Protocol Data Unit (PPDU) scheduling schemes. For example, a PPDU scheduling scheme reduce bandwidth in the channel, thereby dropping the out of band RUs. Front ends provide feedback to a respective radio, which allows that radio to apply the appropriate pre-distortion. The front ends can include one or more filters enabling frequency domain coexistence between collocated radios operating in the differing Wi-Fi bands, and a coupler that provides the feedback indicating the frequency response shift to a radio. The radio can then apply a digital pre-distortion to compensate for the shifting in the rejection band.Type: ApplicationFiled: February 9, 2023Publication date: June 8, 2023Inventors: Nitin A.

Patent number: 11581681Abstract: Example implementations relate to an electronic plug having a locking assembly for securing within an electronic port having a receptacle. The locking assembly includes a cantilever beam, a deformable arm, and an axle rotatably coupled to a connector of the electronic plug. The cantilever beam extends from the axle, where a free end of the cantilever beam includes a locking tab aligned to a recess of the connector. The deformable arm extends from the axle, where an open end of the deformable arm is rested on the connector. In a biased state of the deformable arm, the locking tab is positioned below the recess to allow movement of the connector in and out of the receptacle. In a relaxed state of the deformable arm, the locking tab protrudes above the recess to allow movement of the connector into the receptacle and prevent movement of the connector out of the receptacle.Type: GrantFiled: April 14, 2021Date of Patent: February 14, 2023Assignee: Hewlett Packard Enterprise Development LPInventors: Tri Luong Nguyen, Deven Patel

Patent number: 11516756Abstract: Systems and methods are provided for optimizing the scheduling of Orthogonal Frequency-Division Multiple Access (OFDMA) transmissions in the downlink (DL) direction. A two-stage mechanism can be implemented when effectuating DL OFDMA transmission involving multiple modulation and coding schemes (MCS) in a single transmit burst. A first stage of the two-stage mechanism may use radio frequency (RF) boosting/de-boosting of Resource Units (RUs) such that the average input power to an AP power amplifier (PA) may remain under a saturated PA output power to ensure PA linearity. If RF boosting/de-boosting is not supported, an alternative mechanism for OFDMA grouping (to rigid grouping) can be employed to skip higher MCS.Type: GrantFiled: March 29, 2021Date of Patent: November 29, 2022Assignee: Hewlett Packard Enterprise Development LPInventors: Farhan Hasnain, Mohd Shahnawaz Siraj, Eldad Perahia, Deven Patel, Sachin Ganu

Publication number: 20220260464Abstract: This disclosure provides cyanine dye compounds having linked hydrogen bond-forming groups that can be used for detecting nucleic acids, particularly for fluorescent staining of DNA, in a biological sample. We found that the simultaneous incorporation of at least two hydrogen bond-forming groups (HBGs) into such a nucleic acid stain can provide for crosslinking interactions between the stain and the target nucleic acid, and lead to a significant increase in the detection sensitivity without substantially increasing undesirable cytotoxicity or mutagenicity properties of the dye compounds. The cyanine dye compounds can have a cyanine structure that connects two particular fused heterocycle ring systems, where at least two HBGs are connected to the core structure through linkers. Also provided are nucleic acid complexes including the cyanine dye compounds, and methods of using the compounds to detect nucleic acids in a biological sample.Type: ApplicationFiled: February 16, 2021Publication date: August 18, 2022Inventors: Zhenjun Diwu, Haitao Guo, Lok N.

Patent number: 11356133Abstract: Systems and techniques are described that are directed to filter frequency response shift compensation, including attenuation compensation. Attenuation compensation can apply a pre-distortion to compensate for the magnitude of attenuated resource units (RUs). Additionally, filter frequency response shift can involve applying PHY Protocol Data Unit (PPDU) scheduling schemes. For example, a PPDU scheduling scheme can reduce bandwidth in the channel, thereby dropping the affected RUs. The attenuation compensation is implemented using front ends that provide feedback to a respective radio, which allows that radio to apply the appropriate pre-distortion. The front end can include one or more filters enabling frequency domain coexistence between collocated radios operating in the differing Wi-Fi bands, and a coupler that provides the feedback indicating the frequency response shift to a radio.Type: GrantFiled: April 30, 2021Date of Patent: June 7, 2022Assignee: Hewlett Packard Enterprise Development LPInventors: Farhan Hasnain, Nitin A.
