  • Patent number: 11905152
    Abstract: Traditionally, counterweight fork type autonomous mobile robots (AMR) have been used for any kind of pallet. But the challenge is it occupies lot more maneuvering space while making turns, which cannot work in narrow operating zones. Hence fork over AMR is preferred. However, these fork over AMR have extended parts always touching the ground surface and thus are not suitable for pallets with a wooden plank at the bottom of the fork opening in the pallet. To overcome the above technical problems, an Adjustable Counterweight-based Fork Type Autonomous Mobile Robot (ACFTAMR) is provided that includes chassis assembly and vertical mast unit, a horizontal cross slide mechanism and forks. The chassis assembly is provided counterweight assembly and counterbalance shafts that move forward and backward during pickup and release of payload when the vertical mast unit moves in upward/downward direction, thus providing better stability and counterbalance to the ACFTAMR.

  • Patent number: 11851311
    Abstract: Material handling of packed goods on pallets, roller cages within facilities is in huge volumes and consumes lot of operators' time and efforts. Embodiments of the present disclosure provide an autonomous payload handling apparatus (APHA) that addresses the above material handling process by automating with an intelligent modular robotic platform. The APHA includes fork assemblies that slides alongside of the pallet for better balance over payload and maintains smooth navigation. The fork assemblies equipped with contact/vision sensors that enable APHA to determine whether there is any offset or any contact between surfaces of APHA and/or pallet. The fork assemblies capture sensor data of surrounding object(s) during navigation, size of payload, and pallet, etc. The captured sensor data enables the APHA to correct its offset and/or compute a mode of approach (e.g., navigating angle, deviating from obstacle(s), sliding through pallet/roller cages, and the like) to handle payload(s).

  • Publication number: 20230395108
    Abstract: Systems and methods disclosed herein provide for selectively activating or deactivating one or more memory of a memory array, such that related data path logic of deactivated memory dies neither detects nor processes control signals or data signals for data operations. Examples of the systems and methods provided herein operate to detect a first enable signal at a memory die and detect a first data signal on input/output (I/O) receivers of the memory die. Responsive to detecting at least the first enable signal, a bit value encoded in the first data signal is latched to obtain a first bit pattern. A second bit pattern is obtained, and, based on a comparison of the first bit pattern to the second bit pattern, the I/O receivers of the memory die are activated.

  • Publication number: 20230386584
    Abstract: Systems and methods are provided for correcting errors in unmatched memory devices. Various embodiments herein train a memory interface to determine a duty cycle timing for a clock signal in a data window formed by a data signal in a memory cell. The duty cycle timing identifies an initial trained timing in the data window at which a setup portion and a hold portion of the data window are approximately equal in length when the trigger signal is received at the initial trained timing. The embodiments herein also identify an event that shifts the duty cycle timing away from the initial trained timing, and triggers a retraining of the memory interface based on a determination that at least one of two points defined about the initial trained timing fails a two-point sampling.

  • Publication number: 20230386531
    Abstract: A command/address sequence associated with a read/write operation for a memory device utilizes various existing command/address clock signals in a novel way that obviates the need to utilize the I/O bus. As such, the command/address sequence can be performed in parallel with the DIN/DOUT operations, thereby removing the performance bottleneck that would otherwise be caused by the command and address sequencing. The command/address sequence encodes bit information on first and second enable signals and utilizes rising or falling edges of a clock signal to latch the encoded bit information, which can then be decoded to determine corresponding command and address codes. A chip select sequence is also disclosed that enables a memory chip configuration to be employed in which each chip in a package shares a common connection to a controller but does not require hard-coded pins for performing chip select.

  • Publication number: 20230377677
    Abstract: Techniques for mitigating/eliminating the impact of duty distortion caused by delays in clock paths within a built-in high-frequency test circuit for NAND flash are disclosed. By mitigating or eliminating the impact of duty distortion, accuracy of the valid data window measurement is ensured. Rising edges of a strobe clock signal and an inverted strobe clock signal are used to respectively locate even and odd data (or vice versa) within an input buffer of the NAND flash during respective sweeps of the strobe and inverted strobe clock signals. In this manner, even if the strobe clock signal's duty ratio is distorted, there is no impact on the valid data window measurement. Further, read latency is used to introduce delay to a read enable (RE) clock signal, thereby obviating the need for a replica controlled delay in the RE clock path and eliminating the duty distortion that would otherwise occur.

  • Publication number: 20230286319
    Abstract: State of the art track width adjustment mechanism fail to support track width adjustment while vehicle is in motion. They also require manual intervention, which causes inconvenience. The disclosure herein generally relates to wheel track adjustment, and, more particularly, to a changeable wheel track mechanism for track width adjustment (referred to as TWA mechanism). The TWA mechanism includes a steer and drive unit, a plurality of links, and a sliding unit. The TWA mechanism allows movement of a wheel in inward and outward directions, causing the track width adjustment. The track width is achieved by changing the wheel position to be at a wider position, or a narrower position, or any intermediate position. The TWA mechanism may be associated with any vehicle for which the track width adjustment is to be achieved.

  • Patent number: 11723450
    Abstract: Conventionally, cleaning of objects has been proposed by use of gloves wherein objects need to be pre-washed manually. However, the level of cleaning is not spotless. Electric scrubbers have also been proposed in solving scrubbing problem but are not efficient. Embodiment of the present disclosure provide a glove that integrates a detachable power-driven scrubber. The power-driven scrubber is configured to controllably rotate in one or more directions based on an activation of a sensor to clean an object. The glove further includes sensing mechanisms for controlled flow of water discharge and controlled flow of cleansing fluid dispense that enables the detachable power-driven scrubber to clean the object. Rotation of the detachable power-driven scrubber is controlled and driven by a drive shaft that transmits rotary motion/torque generated by a motor coupled thereto. A scrubber locking strap is provided on the glove for lock and release of the detachable power-driven scrubber accordingly.
