A endovascular graft having sensing devices attached thereto to facilitate measurement of pertinent parameters within the vasculature into which the graft is implanted. Power sources and transmitters may be attached to the graft to facilitate transmission of measurements to a receiving device outside the patient's body. The sensing devices, may be electrically passive or integrated devices with measurement and transmission capability. The sensing devices may be attached to specific locations on the graft material or attached to the lumen, thereby providing pertinent parameters from critical points inside the vasculature, or may be dispersed over the surface of the graft material or within the lumen to provide a profile of pertinent parameters. The sensing devices may be attached to the graft material with one suture using a running stitch to minimize graft bulk and may be coated with a material to inhibit or control tissue growth.

The invention provides devices and methods for performing less-invasive surgical procedures within an organ or vessel. In an exemplary embodiment, the invention provides a method of closed-chest surgical intervention within an internal cavity of a patient's heart or great vessel. According to the method, the patient's heart is arrested and cardiopulmonary bypass is established. A scope extending through a percutaneous intercostal penetration in the patient's chest is used to view an internal portion of the patient's chest. An internal penetration is formed in a wall of the heart or great vessel using cutting means introduced through a percutaneous penetration in an intercostal space in the patient's chest. An interventional tool is then introduced, usually through a cannula positioned in a percutaneous intercostal penetration. The interventional tool is inserted through the internal penetration in the heart or great vessel to perform a surgical procedure within the internal cavity under visualization by means of the scope. In a preferred embodiment, a cutting tool is introduced into the patient's left atrium from a right portion of the patient's chest to remove the patient's mitral valve. A replacement valve is then introduced through an intercostal space in the right portion of the chest and through the internal penetration in the heart, and the replacement valve is attached in the mitral valve position.

The invention provides an intelligent spraying method based on image processing and a spraying robot based on image processing. Through the method, the spraying robot can correctly distinguish specific crops and weeds and carry out targeted spraying according to the distribution condition of the crops and the weeds needing to be sprayed, that is, the spraying robot sprays weed killer on the weeds and sprays corresponding disinfectant and other pesticides on the crops, and consequently intelligent spraying without human interference is achieved. Meanwhile, a wireless video transmission mode is additionally adopted, and a worker can monitor and control the spraying robot by holding a monitor in hand. Thus, the intelligent spraying robot not only reduces the labor intensity of the workers and spraying cost but also reduces the use quantity of the pesticides and pesticide residues in the soil environment and has an immeasurable significance in improving spraying intellectualization and modernization of agriculture and accelerating agriculture precision in our country.

The invention relates to an automatic fast test tube cover taking robot and a cover taking method. The robot comprises a base, wherein an X-axis mechanical arm for controlling movements in front and back directions is arranged on the base, a Z-axis mechanical arm for controlling up and down movements is vertically arranged on the X-axis mechanical arm, a Y-axis mechanical arm for controlling left and right movements is vertically arranged on the Z-axis mechanical arm, and a cover taking mechanical hand is arranged on the Y-axis mechanical arm; and a mechanical arm rotation driving mechanism is arranged at one end of the cover taking mechanical hand, and a cover taking mechanism is arranged at the other end. The automatic fast test tube cover taking robot can automatically complete a cover taking task of a blood collection test tube, can adapt to blood collection test tubes and test tube racks in different specifications, and can recover test tube covers.

A helmet for displaying environmental images in critical environments, comprising at least one video camera and a display for displaying environmental images; the helmet also has a supporting structure that can be anchored to the helmet in order to support the at least one video camera and the display; the supporting structure has a front adapter that can be coupled to a front edge of the helmet, a rear adapter that can be coupled to a rear edge of the helmet, and a connecting element for mutually connecting the front adapter and the rear adapter.

A single trip multizone time progressive well treating method and apparatus that provides a means to progressively stimulate individual zones through a cased or open hole well bore. The operator can use pre-set timing devices to progressively treat each zone up the hole. At each zone the system automatically opens a sliding sleeve and closes a frangible flapper, at a preselected point in time. An adjustable preset timing device is installed in each zone to allow preplanned continual frac operations for all zones. An optional “Stand-Down-Mode” can be integrated into the timing system so that if pumping stops the timers go into a sleep mode until the pumping resumes. The apparatus can consist of three major components: a packer, a timing pressure device, and a sliding sleeve / isolation device. The packer may be removed.

A system, method, and apparatus is provided for estimating a risk of falls from pressure sensor data and inertial sensor data. A classifier function may be generated to relate the inertial sensor and the pressure sensor data with the falls risk (e.g., falls risk or prospective falls data) of the person who generated the pressure sensor data and inertial sensor data. The classifier function may be used to predict a person's risk of falls based on inputs of pressure sensor data and inertial sensor data. Separate classifier functions may be generated for men and women, or separate classifier functions may be generated for patients who closed their eyes while data was being collected and for patients who opened their eyes while data was being collected.

The invention provides a neck-worn sensor that is a single, body-worn system that measures the following parameters from an ambulatory patient: heart rate, pulse rate, pulse oximetry, respiratory rate, temperature, thoracic fluid levels, stroke volume, cardiac output, and a parameter sensitive to blood pressure called pulse transit time. From stroke volume, a first algorithm employing a linear model can estimate the patient's pulse pressure. And from pulse pressure and pulse transit time, a second algorithm, also employing a linear algorithm, can estimate systolic blood pressure and diastolic blood pressure. Thus, the sensor can measure all five vital signs along with hemodynamic parameters. It also includes a motion-detecting accelerometer, from which it can determine motion-related parameters such as posture, degree of motion, activity level, respiratory-induced heaving of the chest, and falls.

The present invention is directed to compositions and methods for treating presbyopia, mild hyperopia, and irregular astigmatism. The compositions include a cholinergic agent, such as a muscarinic acetylcholine receptor M3 agonist, and an alpha agonist having an imidazoline group or a non-steroidal anti-inflammatory agent (NSAID) having COX-2 selectivity. It has been found that an alpha agonist having an imidazoline group or non-steroidal anti-inflammatory agent (NSAID) having COX-2 selectivity in combination with a cholinergic agent, such as pilocarpine, act synergistically to improve the accommodative and focusing ability of the eye while minimizing the side effects from each compound.
