Disclosed is a fingerstall oximeter comprising an upper housing (), a middle housing (), a lower housing () and a detection unit. The upper housing (), the middle housing () and the lower housing () are connected in turn. The lower housing () is made of silica gel, and a finger accommodating chamber () for accommodating a finger to be measured is formed between the opposed surfaces of the lower housing () and the middle housing (). The fingerstall oximeter has high measurement accuracy and small volume, and is easy to disassemble and carry.

Methods, computer systems, and computer-storage medium for generating a per-document index used for semantic searching is provided. A document is received and parsed into a plurality of section. Each term in each section is translated in order to at least one of a cache index or a term identifier. Subsequent to translating the terms, each section is separately group encoded to generate the per-document index. The per-document index is stored in association with a data store.

Per-document index for semantic searching

The present invention discloses a soft gum fingerstall oximeter without pivot structure, the soft gum fingerstall oximeter comprises a soft gum fingerstall which can wraps around a finger closely with variations of the profile of the finger and causes a clamping force distributed on the clamped portion of the finger uniformly. An emission circuit board and a reception circuit board are provided in the soft gum fingerstall. The soft gum fingerstall of the oximeter is enclosed, which can shield light entering from a side.

Finger-clipped pulse oximeter

A portable electrocardiograph, in which an exposed electrode is arranged on the end face of one end of a housing, characterized in that: the other end of the housing is of a comfortable structure for holding; the comfortable structure for holding is provided with the other exposed electrode; and the geometric center of the comfortable structure for holding is of an offset toward the other end of the housing and one of the two transverse sides, and a measuring key is arranged in the geometric center of the comfortable structure for holding. The present invention is of a humanized and unique holding structure shape, which ensures the wrist, the arm, and the trunk of the user are closed to form a relative space, thus allowing the user to measure in natural and correct posture so as to make sure the monitored data to be accurate and reliable.

Portable electrocardiograph

A portable electrocardiograph, characterized in that a clamping cover which tends to close automatically is provided on one end of a housing; a finger hole is provided between the clamping cover and the housing; a lower half of the inner wall of the finger hole is defined on the housing; an upper half of the inner wall of the finger hole is provided on the clamping cover; the lower half of the inner wall is provided with a first electrode; the other end of the housing is provided with a second electrode; and the back face of the housing is provided with a third electrode, in which the first electrode or the third electrode is a neutral electrode. According to the present invention, at least one portion of at least one of the middle finger, the so-called ring finger, and the little finger of the user's hand for grasping the electrocardiograph can contact the neutral electrode, such that the error of the measured result caused by electrical potential fluctuation on the measured person's body can be eliminated.
