Various arrangements for handling a potential security situation using a home automation system are presented. During a defined active monitoring time period, a biometric measurement of a user may be received. The biometric measurement of the user may exceed a defined threshold value for the biometric measurement. A security alert from a home automation device in wireless communication with the home automation host system may be received. If the time period between the biometric measurement is within a threshold time period of the security alert being received a security response action may be performed.

The detector for a surface measuring device includes: an arm including a contact at a tip end of the arm; a rotation shaft configured to rotatably support the arm; a transmission part having one end connected to the arm at a position on a side opposite to the contact with respect to the rotation shaft; an elastic part having one end connected to another end of the transmission part and configured to generate a measuring force to be applied to the contact; a position adjusting part connected to another end of the elastic part and configured to move a position of the another end of the elastic part in a moving direction; and a tilt adjusting part connected to the arm and including a contact part arranged at position where the contact part can be brought into contact with the transmission part.

A tag assembly for measuring a characteristic of a tree includes a band and a shield strip. The band is configured to encircle the tree and has a plurality of tags spaced apart along the band. The shield strip extends along the band to thereby shield a number of tags in the plurality of tags such that the plurality of tags includes shielded tags and unshielded tags. The shield strip prevents the shielded tags from being read or emitting signals and while the unshielded tags can be read or emit signals such that the characteristic of the tree can be determined.

A control method of surface characteristic measuring apparatus relatively displaces by a relative displacement mechanism, detects when the distal end of the stylus contacting the measurable surface, calculates an amount of relative displacement in the Z-axis direction between the measuring device and the measured object required for a measuring arm to be leveled after the distal end of the stylus contacts the measurable surface, calculates a displacement amount generated in the distal end of the stylus in an X-axis direction when the measuring device and the measured object are relatively displaced only by in the Z-axis direction; and levels the measuring arm by relatively displacing only by the measuring device and the measured object in the Z-axis direction by the relative displacement mechanism, and relatively displaces only by the measuring device and the measured object in the X-axis direction by the relative displacement mechanism at the same time.

An automatic measuring device includes a micrometer including a spindle that moves forward and backward to be brought into contact with or away from a workpiece and a displacement detector unit that detects displacement of the spindle, and an automatic operation unit that automates the forward and backward movement of the spindle by power. The automatic operation unit performs a first forward-movement step of moving the spindle forward to bring the spindle into contact with the workpiece, and a contact determination step of determining the contact between the spindle and the workpiece in the first forward-movement step. In the contact determination step, the spindle is determined to be in contact with the workpiece when a change in a position of the spindle detected by the displacement detector unit in the first forward-movement step becomes equal to or less than a predetermined contact determination threshold.

A positioning apparatus for positioning a tactile or optical roughness sensor, a probe or some other measuring instrument with respect to a workpiece can be secured to a movement device of a coordinate measuring machine. The positioning apparatus has a drive that produces a relative movement between two parts of the positioning apparatus, and an inhibiting device, which inhibits the relative movement between the two parts. For this purpose, the inhibiting device has a first friction element and a second friction element each having unlubricated friction surfaces. The friction surfaces are pressed against one another with a normal force that is not variable during the operation of the positioning apparatus. A coefficient of sliding friction that is less than 0.15 acts between the friction surfaces in the case of dryness and without lubrication. Typically, the inhibiting device is arranged in a flexspline of a strain wave gearing.

The present invention relates to a device for measuring an object, comprising a winder of a measuring element arranged to form a loop about the said object, which has at least one wall and an exit opening arranged to allow the exit of at least one unwound portion of the said measuring element, which is defined between the said exit opening and a distal end of the said measuring element, which is provided with a connecting element that abuts against the said exit opening, and a connecting means being located at a distance d from the said exit opening, characterised in that the said connecting means is located on the said at least one wall, is adjacent to the said exit opening, is presented in the form of a protrusion which extends towards the said distal end, and is arranged to receive the said connecting element in a stationary manner.

Provided herein are various embodiments of an improved device for accurate measurement along a desired axis that is tolerant to off axis movement and other environmental factors. The measurement relies on a conversion from linear displacement of a tensile element in a pulley system which is monitored by a low power rotational encoder. The orientation and mechanical architecture of the device is set to reduce the impact of off-axis movement or forces on the measurement of interest. A computing unit determines the distance measurement by determining the state of rotation in the system in the context of the system's specific design, without the need to constantly monitor the sensor.
