International Classification:

F15B 15/00

US Classification:

60452

Abstract:

An actuator control system is disclosed. The actuator control system may have a pump and at least one actuator. The actuator control system may further have an actuator valve configured to control the at least one actuator. The actuator control system may also have a pump pressure sensor configured to determine a pump pressure value and a load pressure sensor configure to determine a load pressure value. The actuator control system may additionally have a controller configured to receive the pump pressure value and the load pressure value. The controller may further be configured to compare the pump pressure value and the load pressure value, and selectively implement a primary control strategy and a secondary control strategy based on the comparison.

International Classification:

G01B 3/1043
G01B 3/1056

Abstract:

A measuring tape device may include a housing having an aperture, a reel assembly enclosed within the housing, and a blade having a first end configured to extend from the housing through the aperture and a second end configured to be wound on the reel assembly. The housing may include a first case half and a second case half. The reel assembly may be configured to alternately allow the blade to be withdrawn from the reel assembly through the aperture or received in the aperture onto the reel assembly. The first case half and the second case half may be joined together via threaded fasteners inserted into respective portions of screw bosses formed in corresponding portions of the first and second case halves. Mating features may be provided on the first and second case halves to facilitate joining the first and second case halves. At least some of the mating features may be longer than others of the mating features, or a diameter of the screw bosses is about 1.5 time to about 2.5 times larger than a diameter of the threaded fasteners.

International Classification:

G01B 3/1003
B24C 1/10
B24C 3/12
G01B 3/1056

Abstract:

A blade for a measuring tape device may include a first end configured to extend from a housing of the measuring tape device through an aperture, a second end configured to be wound on a reel assembly within the housing, and a first cupped portion having a first amount of cupping over a selected portion of a longitudinal length of the blade. The first cupped portion may be defined by a curved portion extending from an apex of the curved portion toward lateral edges of the blade, and wings extending from each of the lateral edges toward the curved portion on each side of the apex. The curved portion includes a first radius proximate to the apex of the curved portion, and a second radius at a point spaced apart from the apex on both sides of the apex, the second radius being different than the first radius.

Inventors:

- Apex NC, US
Vlad Petru Patrangenaru - Ellicott City MD, US

International Classification:

G01B 3/1003

Abstract:

A method of producing a measuring tape may include providing a tape measure blade having a first end configured to extend from a housing and a second end configured to be wound on a reel assembly, defining a first non-critical region from the first end to a start of a critical region, defining a second non-critical region from the second end to an end of the critical region, and modifying a mass per unit length of a portion of the blade such that a mass per unit length of the first and second non-critical regions is less than a mass per unit length of the critical region.

Abstract:

An example distance measuring apparatus is provided. The example apparatus may include a measuring tape with distance measurement indicia, a camera, and processing circuitry. The processing circuitry may be configured to cause the camera to capture an image of the measuring tape, and determine a measurement by analyzing the captured image. The measurement may be determined based on the distance measurement indicia of the measuring tape within the image at a measurement position. The processing circuitry may be further configured to store the measurement in a memory device.
