Having A Movable Contact Probe Patents (Class 33/556)
  • Patent number: 10458450
    Abstract: A probe head of a coordinate measuring machine (‘CMM”) includes a sensor to detect impact of the probe head with a foreign object. The probe head is movably coupled to the CMM such that the sensor detects motion of the probe head relative to a portion of the CMM resulting from an impact event. Some embodiments cause the CMM to take action in response to detecting an impact. Probe clips allow adjustment of the position of a CMM probe relative to the portion of the CMM from which the probe is suspended. This allows the position and orientation of the CMM probe to be adapted to a variety of applications.

  • Patent number: 10434715
    Abstract: In one embodiment of the present invention, a stress analysis engine efficiently computes stresses for an arbitrarily shaped three-dimension (3D) model. In operation, the stress analysis engine slices the 3D model into layers of cross-sections. The stress analysis engine then groups the cross-sections into virtual cross-sections. For each virtual cross-section, the stress analysis engine applies bending moment equilibrium-based equations to determine a corresponding structural stress for the 3D model. The efficiency of this stress analysis process enables real-time feedback of stresses to an interactive design tool that facilitates a trial-and-error design process. Using this trial-and-error process reduces the guesswork and/or over-engineering associated with conventional approaches based on finite element methods that are typically too slow for interactive feedback.

  • Patent number: 8533970
    Abstract: An apparatus for measuring objects, in particular to a coordinate measuring unit, is provided. The unit has a probe which is movable relative to an object to be measured by means of an actuator to sample the surface of the object in a contacting manner, wherein a sampling body, whose front end is designed as a measuring tip for a contact with the object is supported at the probe. The relative position of the measuring tip with respect to the probe is determined. The sampling body is supported at the probe with movement play along at least one direction. A change in the inclination of the sampling body relative to the probe, or vice versa, can be detected via a measurement of a test parameter.

  • Patent number: 8407908
    Abstract: A profile measurement apparatus includes: a probe which includes a gauge head for measuring a profile of an object to be measured and which moves the gauge head within a given range; a movement mechanism which moves the probe; and a controller which measures the profile by controlling the movement mechanism to contact the gauge head against the object. The controller comprises: a movement amount acquisition section which acquires a movement amount of the gauge head from a reference position; a deviation acquisition section which acquires as a deviation the movement amount when the gauge head is in a non-contact state; a determination section which determines whether the deviation is greater than a first threshold value; and a resetting section which, when the deviation is greater than the first threshold value, resets the reference position to a position arrived at by combining the reference position and the deviation.

  • Patent number: 8365426
    Abstract: A coordinate measuring machine for determining spatial coordinates on a measurement object has a frame structure on which a probe head is arranged. The probe head has a probe head sensor system, a body part and a coupling part which can move relative to the body part. The frame structure is designed to move the probe head relative to the measurement object. The probe tool has at least one stylus for making contact with the measurement object, and also has a rotating plate. The stylus is coupled to the coupling part by means of the rotating plate, such that it can rotate. At least one roll motion projection is formed on the body part. The rotating plate can be rolled along this roll motion projection by means of a movement of the coupling part in order to set a defined orientation of the stylus.

  • Patent number: 8290695
    Abstract: Probe data is analyzed to derive Longitudinal Speed Profiles (LSPs) and an Optimal Longitudinal Speed Profile (18) for each road segment or link in a digital map network. The Longitudinal Speed Profiles (LSPs) profiles are calculated during defined time spans whereas the Optimal Longitudinal Speed Profile (18) is based on the LSP for the time span corresponding only to free flow traffic conditions. All of the LSPs can used to create a respective energy cost for each time span, or only the OLSP (18) can be used (or alternatively the RRDSL 16 or LRRDSL 17) to calculate an energy cost for the free flow conditions only. The energy cost can be used to predict the energy required by a vehicle to traverse the link. Navigation software can use the energy cost to plan the most energy efficient route between two locations in the digital map. Sensory signals can be activated if a driver strays from the Optimal Longitudinal Speed Profile (18) to achieve extremely high levels of energy efficiency.
