A lighting device that emits illumination light from two or more angular directions onto a sample surface to be measured, an imaging optical lens, and a monochrome two-dimensional image sensor are provided. This configuration provides a method and an apparatus that take a two-dimensional image of the sample surface to be measured at each measurement wavelength and accurately measure multi-angle and spectral information on each of all pixels in the two-dimensional image in a short time. In particular, a multi-angle spectral imaging measurement method and apparatus that have improved accuracy and usefulness are provided.

Measured efficiency of an air conditioner or heat pump system is needed to accurately evaluate the economics of operating the system to provide a known amount of cooling. Significant degradation of air-conditioner and or heat pump components increases the operating cost by lowering the capacity of the system and/or increasing the power consumption. The invention provides measurement of the energy efficiency of any operating DX cooling, refrigeration, or heating unit, expressed in standard units by measuring the cooling or heating capacity and the power usage.

According to an aspect of the present disclosure, a viewer rating calculation server includes a server communication unit configured to receive first audio feature information extracted by a viewer rating calculation remote apparatus from viewing contents, an audio feature information extraction unit configured to extract second audio feature information of a broadcast content received from at least one broadcast service provider, a viewing content identification unit configured to generate viewing information as a result of determination of a currently viewing content by comparing the first audio feature information with the second audio feature information, and a viewer rating calculation unit configured to calculate a viewer rating of each broadcast content in real time on the basis of multiple pieces of the viewing information.

A method of determining the presence of preeclampsia is provided wherein a determination is made as to whether there has been a substantial elevation in marinobufagenin which may be a blood-derived or urine-derived and if such elevation does exist concluding that preeclampsia does exist in a patient. The method may advantageously be practiced by employing urine, blood serum or blood plasma as the body specimen containing the protein in determining whether a patient has preeclampsia. The method may include subsequent therapeutic patient treatment. Related diagnostic apparatus is also provided.

A screen net includes a front member with an opening, a base member, a catch member and a wall member. The base member is placed on the ground. The catch member is adapted to catch a ball that passes through the opening of the front member. The wall member is positioned above the opening of the front member. The wall member comprises a wall fabric member and a wall pole member. The wall fabric member comprises a sleeve through which the wall pole member passes. The wall fabric member is attached to the front member. The ends of the wall pole member are supported by the base member. The screen net further comprises straps that connect the front member and the base member. The straps are under tension provided by the elastic pole segments.

The present invention relates to a practice golf club capable of adjusting head speed having a head (H) attached to an end of a shaft(S) having a grip (G), from which an impact sound is generated through a swing operation, wherein the head (H) includes: a first body (100) coupled to the end of the shaft (S); a second body (110) having a tubular shape, both ends of which are open and adapted to be screw-coupled to the rear end of the first body (100); a moving weight (140) movably disposed inside the second body (110); a magnet (180) adapted to fix the moving weight (140) to the front end portion of the second body (110) by means of a magnetic force thereof; adjustment means adapted to adjust the gap between the magnet (180) and the moving weight (140) so as to control the strength of the magnetic force of the magnet (180) pulling the moving weight (140); a cap (120) screw-coupled to a rear end of the second body (110); and return means interposed between the cap (120) and the moving weight (140) to return the moving weight (140) to the original position when the moving weight (140) momentarily moves by centrifugal force and collides against the cap (120) to generate an impact sound.

Physical and/or sensory skills may be trained while an individual wears eyewear that alters the quality/quantity of visual information available to the individual. Sensor may measure performance metrics and/or physiological metrics during training During a recovery period, an individual may receive visual information with less alteration of the quality and/or quality of the information. The duration of the recovery period and/or the reduction in altering the quality and/or quantity of visual information provided during a recovery period may be determined based upon the performance metrics and/or the physiological metrics measured during training

An apparatus and methods for golf swing training in order to improve a user's golf swing is disclosed in which a shaft or post is configured to be stabilized by locating an extension of the post into a receptacle, such as a trailer hitch on the back of a car or truck or a separate base unit. At the top of the shaft, a bar is pivotally connected to the shaft at an attachment point, while the other end of the bar is connected to a golf club, so that when a player practices swinging the club, the club remains in the correct position from the beginning to the end of the swinging motion.

A method of determining the presence of chronic volume dependent hypertension is provided wherein a determination is made as to whether there has been a substantial reduction in phosphorylation or concentration of a specific protein which may be a blood-derived protein or renal proximal brush border membrane protein and if such reduction exists concluding that chronic volume dependent hypertension exists in a patient. The method may advantageously be practiced by employing blood serum or blood plasma as the body specimen containing the protein in determining whether a patient has chronic volume dependent hypertension, a cellular component of the blood, such as a blood-derived protein coming from the plasma membrane of lymphocytes. The method may include subsequent therapeutic patient treatment. Related diagnostic apparatus is also provided. The blood-derived protein may be CLAMP.

A posture correcting tool is provided which allows a golf player to practice so that the forward inclination angle of the upper-half body when impacting on a ball with a club can be controlled appropriately and extend the ball flight distance. Being a posture correcting tool worn by a player when practicing club swings, it has a wearing unit which can be fixed to the player's waist a back fitting unit which is rotatably joined with the wearing unit, arranged so that it can fit with the player's back when worn, and can regulate the forward inclination angle of the upper-half body when the player swings a golf club, and an angle indicating unit with which the forward inclination angle can be visually checked.

A golf swing/putting trainer includes a support member including a body shaped like a plate or shaft and having a supporting wall for stopping against the user's body, and a handle including a shaft connected at one end thereof to the center of the body of the support member and having a handhold portion for holding by the user's both hands. Thus, the user can hold the handle with the two hands to abut the supporting wall of the support member against the abdomen, and then twist the waist to practice the backswing and swing actions. Alternatively, the user can hold the handle with the two hands and attach the two lower arms to the two bearing portions of the support member to practice the putting action.

An operation section used to form a liquid ejection device that ejects liquid includes a tubular nozzle section through which the liquid is ejected, and a gripper section in which the nozzle section is so disposed as to protrude through one side of the gripper section and a tube group including a tube through which the liquid flows and a cable through which a drive signal is supplied is connected to another side of the gripper section, and the gripper section is provided with a finger position fixing section on which any of an operator's fingers rests when the operator grips the gripper section.
