A computer-implemented method for creating an activity-optimized cutting guides for surgical procedures includes receiving one or more pre-operative images depicting one or more anatomical joints of a patient, and creating a three-dimensional anatomical model of the one or more anatomical joints based on the one or more pre-operative images. One or more patient-specific anatomical measurements are determined based on the three-dimensional anatomical model. A statistical model of joint performance is applied to the patient-specific anatomical measurements to identify one or more cut angles for performing a surgical procedure. A patient-specific cutting guide is created that comprises one or more apertures positioned based on the one or more cut angles.

An infant sleep device may include a platform for supporting an infant, a base upon which the platform is supported, and one or more weight sensors positioned to measure weight of an infant positioned on the platform.

Systems and methods for generating a 3D model is provided. The methods may include receiving target information relating to the subject acquired by an information acquisition component and generate the 3D model of the subject based on the target information. The target information may include a plurality of images of the subject. The subject may be supported by a scanning table, and the information acquisition component may include a plurality of cameras mounted on a gantry of a medical imaging device. The plurality of cameras may be configured to acquire the plurality of images of the subject from multiple perspectives, and at least one of the plurality of cameras may be configured to acquire an image of a body side of the subject.

A gate apparatus includes an upper light that emits light from above a user, a lower light that emits light from below the user, a light control unit, and an acquisition unit. The acquisition unit acquires biological information about the user. The light control unit changes the luminance of the light emitted from the upper light and the luminance of the light emitted from the lower light when the biological information about the user is acquired.

An image processing device includes: an obtaining unit configured to obtain an image including at least one body hair; and an analyzing unit configured to analyze the image to output information indicating an orientation of the at least one body hair included in the image.

A mouth-opening measuring device includes a first end and an opposing second end. The width of the first end is less than the width of the second end such that the different widths on the first and second ends provide for different mouth opening abilities of an individual when either the first end or the second end is inserted into an individual's mouth.

The present disclosure relates to distance measurement methods and apparatuses. One example method includes receiving multiple first echo signals, determining multiple first spectrum data groups based on the multiple first echo signals, performing normalization processing on a signal strength value corresponding to each distance value comprised in each first spectrum data group to obtain a normalized signal strength value corresponding to each distance value, determining, based on a normalized signal strength value, a variance value of a signal strength value corresponding to each distance value comprised in the multiple first spectrum data ggroups, and determining a distance between a target obstacle on the to-be-measured object and the transmitting origin based on the variance value of the signal strength value corresponding to each distance value comprised in the multiple first spectrum data groups.

A method for operating an accessory device to capture calibration data. The method can include capturing an image of a portion of a user's body that includes the user's stoma and at least two reference locations, and storing distance scale information representative of a distance between the two reference locations. The method further includes processing the captured image, including: identifying the reference locations, identifying the stoma, and generating calibration data representative of one or more stoma parameters as a function of the identified reference locations, identified stoma and the distance scale information. The calibration data can be stored.

A blood pressure detection method is provided. The method comprising: obtaining wrist circumference data, wrist fat thickness data, and blood pressure data and correcting the blood pressure data based on the wrist circumference data and the wrist fat thickness data.

A femoral neck measuring method includes: measuring an affected limb after a femoral stem prosthesis is installed through an optical localization probe, and calculating an actual length of the femoral neck needed by the affected limb according to an osteotomy surface of the affected limb determined after the femoral stem prosthesis is installed; determining a femoral ball prosthesis and a femoral neck prosthesis to be selected according to the calculated actual length of the femoral neck and a length of a femoral neck of a healthy limb measured before surgery; and measuring a length of the affected limb after the femoral ball prosthesis and the femoral neck prosthesis are implanted, and restraining a length difference between the healthy limb and the affected limb by adjusting a length of the femoral neck of the affected limb.
