摘要:
Methods and equipment suitable for measuring dimensions of a cylindrical body including systems having a housing and means for supporting the housing relative to an arcuate surface of the body. The supporting means comprises at least two wheels having axes of rotation oriented so that engaging the arcuate surface of the body with the two wheels causes edges of the two wheels to contact the arcuate surface at two terminals spaced apart by a length of a chord lying in a cross-section plane of the body. Measurement means is mounted to the housing for contacting a surface point of the body located within the length of the chord of the body, and means is provided for determining the diameter of the body based on the length of the chord determined by the two wheels and a height of the chord ascertained with an output of the measurement means.

A facemask package integrated with a mask sizing ruler is disclosed. The package stores the masks of various sizes. The mask sizing ruler comprising a first measuring gauge element, a second measuring gauge element and one or more sizes indicated thereon. The sizes in the sizing ruler are determined by categorizing one or more precisely previously measured distance from at least two points on one or more human faces into one or more sizes based on at least one distance on one or more masks of one or more mask sizes. At least one distance on one or more masks of one or more mask sizes is proportional to the maximum vertical distance of the mask in unfolded state. A system and method for determining the sizes indicated on the mask ruler are also disclosed. The sizing ruler precisely indicates the size of the mask that most appropriate to a user as the sizes are categorized from real human face dimensions.
摘要:
A method and apparatus is disclosed for marking an object (10). For example, the method may be used to produce precision marks (28) for a metrological scale in the form of a stainless steel ribbon (10). A laser (21) is used to produce pulses (e.g. ultra-short pulses) at repeated instants that form markings on the object (10). The apparatus is operated by a controller (200). A reader, e.g. formed by two or more scale readers (23a and 23b), is used to determine the distance between two or more markings produced when the object (10) is subjected to the beam and for issuing a pitch signal to the controller (200). The controller (200) uses the pitch signal to control the repeated instants at which the laser (21) emits its beam.

A robotic mower including a chassis, a cutting motor driving at least one cutting blade, a height adjustment assembly and control circuitry. The height adjustment assembly comprises a height adjustment motor (140) configured to adjust a height of a motor bracket (100) via rotation of a height adjustment screw (136) driven by the height adjustment motor. The motor bracket provides structural support for the cutting motor at an adjustable level relative to the chassis. The control circuitry is configured to control operation of the height adjustment motor for positioning of the motor bracket based at least in part on information received by the control circuitry. The received information may be indicative of an amount of rotation of the height adjustment screw.
摘要:
To provide a measuring instrument having improved usability and viewability. A measuring instrument includes a touch panel display unit that receives an external input performed by physical contact and has a display function. In the touch panel display unit, a plurality of operation icons that are used to perform a complicated input operation as well as a measurement result are displayed. It is possible to provide a measuring instrument that is superior in terms of the usability and viewability. For example, a measurement mode can be selected by selecting and touching one of the plurality of operation icons displayed in the touch panel display unit.
