A golf system includes a plurality of striking areas, each striking areas being associated with a respective set of targets. The golf system includes at least one sensing device for sensing one or more parameters regarding the travel of a physical golf ball. A processor is configured to: access a database including golf hole data, the golf hole data defining relative positions of a tee-off location and a pin location for a virtual golf hole; based on the one or more parameters regarding the travel of the physical golf ball, update a virtual location of a virtual golf ball; generate signals to provide an indication of which of the plurality of striking areas or corresponding set of targets a next shot is to be struck from or to; and generate signals to provide an indication of which target in a set of targets represents a direction of the pin location.

An Internet of Thing (IoT) device includes a camera coupled to a processor; and a wireless transceiver coupled to the processor. Blockchain smart contracts can be used with the device to facilitate secure operation.

A method of predicting the likelihood of a post T-off golf swing or consecutive swings resulting in a ball being sunk in a hole; the method utilising communication equipped cameras or communication equipped laser rangefinders at known locations to determine accurate ball lie information. Transmission of this location information in real time to a processing facility linked to a database of historical play information incorporating at least ball position information and golf course in order to calculate odds of success of the upcoming swing and/or subsequent swings.

A wood-type golf club head includes first and second ribs projecting from a bottom club head wall portion, the wall portion, the first rib, and the second rib forming an elongate recess defining a weight path. A weight element is translatable along the weight path and includes a first weight portion, a second weight portion, and a fastener, the first and second ribs each being interposed between the first weight portion and the second weight portion such that the first weight portion is located proximate the club head wall portion and the second weight portion is located distal the club head wall portion. The second weight portion has a contact surface that includes a recessed region, and when the weight element is in a secured position, at least a portion of the first weight portion is located within the recessed region.

A system includes a minimally intrusive display system (MIDS) configured to be disposed on an eyewear. The MIDS includes a display system and a sensor system configured to provide for a sensor data. The MIDS further includes a processor configured to process the sensor data to derive an activity metric. The processor is further configured to display, via the display system, the activity metric, wherein the display system is disposed in the eyewear so that the activity metric is only viewed when a user of the eyewear turns the user's pupil towards the display system at angle a from a forward direction.

An Internet of Thing (IoT) device includes a body with a processor, a camera and a wireless transceiver coupled to the processor.

The technology disclosed here involves analyzing an activity session. An example method involves receiving activity data indicative of an activity of a user, the activity data comprising a plurality of measurements associated with multiple parameters monitored during an activity session; retrieving a set of criteria corresponding to an activity type, wherein the set comprises a criterion related to a biomedical parameter and a criterion related to a resistance parameter; classifying, based on the set of criteria, the received activity data into a plurality of segments, wherein a first segment comprises a portion of the activity data corresponding to the activity type; accessing historical data associated with the user, the historical data comprising a second segment of historical data corresponding to the activity type; comparing the first segment comprising the portion of the received activity data and the second segment comprising historical data; and generating output based on the comparing.

A golf system includes a striking area; a target area including a plurality of physical targets positioned at different locations relative to the striking area; and at least one sensing device for sensing one or more parameters regarding the travel of a physical golf ball. A processor is configured to: access a database including golf hole data, the golf hole data defining relative positions of a tee-off location and a pin location for a virtual golf hole; based on the one or more parameters regarding the travel of the physical golf ball struck from the striking area, update a virtual location of a virtual golf ball on the virtual golf hole; and generate signals to provide an indication of which of the plurality of physical targets represents a direction of the pin location based on the virtual location of the virtual golf ball and the locations of the physical targets.

Systems, methods and computer-readable media are provided for determining an effective altitude in relation to a moving sports object. In some examples, a method includes determining respective values for an air temperature, an air pressure, and a relative humidity of an environment of interest. Based on the determined respective values of the air temperature, the air pressure, and the relative humidity, an air density for the environment of interest is calculated to derive a first air density value. A second air density value is derived for a reference environment. An absolute value of a difference between the first and second air densities is compared against a preset comparison value and, based on the comparison being equal to or smaller than the preset comparison value, an output including an indicator of the effective altitude is generated.
