  • Patent number: 11203925
    Abstract: In the present disclosure, by providing a rotary torque sensor and an auxiliary drive mechanism, the drilling drive can be well controlled according to the required torque. For example, when encountering rock formations, the auxiliary drive mechanism can be used for simultaneous driving drilling, and when drilling in soft formations, only by disconnecting the transmission can the operation be completed, so as to effectively reduce energy consumption and improve utilization. In the present disclosure, when a rotary torque is greater than a set value, the controller controls the auxiliary drive mechanism to transmit to the main drive column and drive the main drive column, and when the rotary torque is smaller than or equal to the set value, the controller controls the power transmission between the auxiliary drive mechanism and the main drive column to be disconnected.

  • Publication number: 20210088982
    Abstract: A method for designing and tuning a PID process controller includes approximating a process as a second order process but in a manner that includes the effects or characteristics introduced by various different devices in the I/O network, and using a lambda tuning method to determine tuning parameters or coefficients for the PID controller. The enhanced controller design and tuning method provides a systematic manner of achieving performance improvement of PID controllers within a process control system and is effective at overcoming challenges arising from signal aliasing, the use of anti-aliasing filtering and the effects of different I/O settings of both traditional and advanced I/O marshalling architectures.

  • Patent number: 10802979
    Abstract: Systems and techniques for dynamic code execution location in heterogeneous memory are described herein. In an system having a first class of memory and second class of memory that are both byte-addressable, an interpreter may be initialized to execute a program from the first class of memory. The initialization may include locating an Interpreter Routine Address Table (IRIT) in the second class of memory and creating counters for routines in the IRIT. A counter for a routine may be modified as it is referenced from the IRIT during execution. The routine may be moved from the first class of memory to the second class of memory in response to the counter passing a threshold. An entry in the IRIT for the routine may be updated with an address in the second class of memory corresponding to the routine.

  • Publication number: 20200073905
    Abstract: Technologies for cross-device shared web resource caching include a client device (102a) and a shared cache device (102b). The client device (102a) scans for a shared cache device (102b) in local proximity to the client device (102a) and, in response to the scan, registers with the shared cache device (102b). After registering, the client device (102a) requests a cached web resource from the shared cache device (102b). The shared cache device (102b) determines whether a cached web resource that matches the request is installed in a shared cache (102b). The shared cache device (102b) may determine whether an origin of the request matches the origin of the cached web resource. If installed, the shared cache device (102b) sends a found response and the cached web resource to the client device (102a). If not installed, the shared cache device (102b) sends a not-found response and the client device (102a) may request the web resource from a remote web server. Other embodiments are described and claimed.

  • Patent number: 10375782
    Abstract: An LED arrangement uses a tapped driver driven by a rectified mains input and placed over a light output surface. There are at least first and second groups of LEDs on the light output surface. The total light output density for the LEDs of the second group (which are turned on for less of the mains cycle) per unit area of the light output surface is greater than the total light output density for the LEDs of the first group per unit area of the light output surface. A fraction of a light emitting surface of the second group (16) of LEDs to a second area (20B) of the light output surface occupied in a macro view by the second group (16) of LEDs, is larger than a fraction of a light emitting surface of the first group (14) of LEDs to a first area (20A) of the light output sur face occupied in a macro view by the first group (14) of LEDs. This means the light output density when averaged over time is made more consistent between the two (or more) groups of LEDs.

  • Patent number: 10362125
    Abstract: Technologies for pre-action execution include a client computing device to request a resource from a server and receive content from the server including the requested resource and one or more pre-action hints. Each of the one or more pre-action hints identifies a suggested pre-action to be taken by the client computing device prior to receipt of a corresponding user request to perform the corresponding suggested pre-action. The client computing device determines a likelihood of success of one or more pre-actions based on historical behavior data of a user of the client computing device, wherein each pre-action corresponds to at least one of the one or more pre-action hints. The client computing device selects a pre-action to execute based on the determined likelihood of success of the one or more pre-actions.
