Seat position

The seated position is generally preferred when using nitroglycerin since the drug may cause dizziness. 

A drawer, or a set of drawers, situated within easy reach of the seated position, is useful for holding small tools, cork stoppers and other accessories. 

While some glassblowers prefer to stand at the bench it is considered good practice to sit when working. Again there are many who prefer a comfortable chair with a padded seat and back rest. In general, a laboratory stool is all that is necessary. In the seated position the elbows should rest comfortably on the bench top, just in from the edge. Both feet should be on the floor. An easy elbow position is essential. Should this need a stool of such height that one s feet do not reach the floor they may be rested side by side on a stool leg brace. 

Blood samples. Blood samples should be standardized to be taken in tlie seated position whenever possible. If this... 

Characteristically the pain is deep-seated, positional, frequently nocturnal, and unresponsive to medication. The intensity of the pain varies from mild to severe, and does not usually correlate directly with the inflammatory process or other physical findings. Severe attacks last from several days to several weeks and may be aggravated by eating. 

Rise slowly from a seated position to prevent hypotension.

A control by which the driver applies the emergency brake system must be located so that the driver can operate it from the normal seating position while restrained by any seat belts with which the vehicle is equipped. The emergency brake control may be combined with either the service brake control or the parking brake control. However, all three controls may not be combined. 

Studies of the antro-pyloro-duodenal region are performed with the ultrasound probe positioned at the level of the transpyloric plane, and the antrum, the pylorus and the proximal duodenum are visualized simultaneously. The subjects are studied in a seated position, with a 3.5- to 5-MHz transducer.

Eliminate any seating design that would lead to or would transmit 3 to 4 cycles per second vibrations, since the resonant frequency of the human vertical trunk in the seated position is between 3 and 4 cycles per second. 

You are to design a computer workstation that includes use of a keyboard from a seated position. Identify the recommended dimensions or range of dimensions for the following ... 

No less important is to make the properties of the sound system in the vehicle in the way that an optimal subjective perception is achieved for every passenger at every interior variant. Here, both the position (driver seat, passenger seat, rear seat) and the fine adjustment of the seat position have great importance. 

This is an area for FDMU that the acoustics of the vehicle interior is depicted for each vehicle variant for each passenger in each seat position to ensure that decisions on the design of the overall system can be represented entirely. The scenario describes a system for automatic volume control of (at least) two active sound sources. In this scenario, a person is in the vicinity of the two sound sources. His position, and, therefore, the distances from the sound sources can be changed. Both sound sources emit varying signals, e.g. music from a stereo system. In the area noise is present too, compromising the clarity of the music. Another part of the system is a microphone which detects the total sound pressure in the interior of the vehicle. Total sound pressure is composed of both the music and from the noise. 

The user inputs data in the design table with the position and kinematics of seats. These data affect the behavior as weU as the geometry in the selected use case. The user can change the CAD model if necessary, without influencing the behavior. The body height of the human as weU as his seat position (driver, passenger, rear seat) are parameters, too. The hst of parameters is closed by the geometrical position of the loudspeakers and the microphone in the context of a car interior. 

A horizontal beam technique may also be used with the joint either held at the child s side away from the body or raised and supported on foam pads with the child in a seated position. 

All tools, equipment, or components required to perform the tasks are easily reached from the seated position... 

Reaching overhead or at levels below seated positions is required— especially when forward or side position reaches must be accomplished at a variety of levels above the work surface (adapted from Eastman Kodak, 1983)... 

The beam path of the laser must be located and secured above or below eye level for any standing or seated position in the facility. 

Many competitive manufacturers in the automotive industry have employed ergonomics in designing cars for comfort, safety, and efficiency. Examples include options for driver seat position to accommodate variation in body size and allow the steering wheel and backrest to be ergonomically positioned. Also noted are passenger-seat comfort and safety... 

The test load shall be applied as shown in Figure W-27, with the seat positioned as specified in 29 CFR 1926.1002(d)(4). Loading cylinders shall be mounted pivotally at both ends. Loads applied by each cylinder shall be equal within two percent, and the sum of the loads of the two cylinders shall be two times the tractor weight as set forth in 29 CFR 1926.1002(e)(1). The maximum width of the beam illustrated in Figure W-27 shall be 6 in. (152 mm). 

Attention needs to be given to the seating positions, both in relation to relative height and layout (if the interview is conducted while seated). An interviewer can interpose a desk or choose not to. What difference does this make to the atmosphere of an interview ... 

Many jobs require performance of tasks in the seated position. Constant sitting in poorly designed chairs, in stressful postures, to carry out visual or manipulative tasks is a common source of recurrent or persistent back pain. Appropriate worlq)lace and chair design promote maintenance of correct posture and the prevention of postural strain. 

However, another reader may not be so confident in the chair and will change seating positions to the sofa. Other persons may view the same risk situation differently. Reconciling different views to gain a common agreed response or control measure is challenging.
