    • In an eye test apparatus of the type having a single examination area, an improved view port is disclosed having a view port casing and a mounting apparatus arranged so that the view port casing is movable between a first and second active positions. In a first active position, the casing receives a patient's forehead so that a patient's right eye is aligned with a examination area, and a second active position wherein a casing receives a patient's forehead so that a patient's left eye is aligned with the examination area. The casing is specially configured to occlude ambient light and to accommodate a patient wearing eyeglasses. The eye test apparatus may further have a position sensor system for sending the present position of the casing. In one embodiment of the invention, a control unit is provided which is responsive to the position sensor system so that administration of a test to a patient is permitted only if the casing is in an active position, and may further be made responsive to the sensor system so that data captured during the test by the control unit is automatically categorized according to which eye is currently being tested.
    • 在具有单个检查区域的类型的眼睛测试装置中,公开了一种改进的视野端口,其具有视口端口壳体和安装装置,其布置成使得视口端口壳体可在第一和第二活动位置之间移动。 在第一活动位置,套管接收患者的前额,使得患者的右眼与检查区域对齐,以及第二主动位置,其中壳体接收患者的前额,使得患者的左眼与检查区域对齐。 外壳被特别地配置成遮挡环境光并容纳佩戴眼镜的病人。 眼睛检查装置还可以具有用于发送外壳的当前位置的位置传感器系统。 在本发明的一个实施例中,提供一种控制单元,其响应于位置传感器系统,使得仅当外壳处于活动位置时允许对患者进行测试,并且还可以响应于传感器 系统,使得控制单元在测试期间捕获的数据根据​​目前正在测试的眼睛进行自动分类。

    • A hand-held compact diagnostic device is provided with a pair of instrument heads each requiring an independent source of illumination. The instrument heads may be rotated into a fully extended position and once therein, may be smoothly turned through 360 degrees in consecutive ninety degree intervals to accommodate any preferred orientation desired by the user. Each instrument head is biased in the fully extended position and a rotated closed position. Each instrument head is also adjustably biased to an aligned position for proper closure by the interaction of an adjustment collar with a pair of ball detents. The adjustment collar further biases each head in three additional positions at ninety degree intervals for use when fully extended. A pair of central terminals maintain continuous contact between each rotatable head of the device while a pair of radial terminals are in electrical contact only when the instrument head is in a fully extended position. When the instrument head is rotated into the closed position, the radial terminals disengage to open the circuit between the source of illumination in the instrument head and a battery source contained within the device.
    • 手提式小型诊断装置具有一对仪器头,每个仪器头需要独立的照明源。 仪器头可以旋转到完全伸出的位置,一次可以顺利地以连续的九十度的间隔360度旋转,以适应使用者期望的任何优选的方向。 每个乐器头被偏置在完全伸出的位置和旋转的关闭位置。 每个乐器头还可调节地偏置到对准的位置,以通过调节环与一对球形棘爪的相互作用来适当地关闭。 调整套环进一步将每个头部以三十度的间隔三个附加位置偏置,以便在完全伸展时使用。 一对中心端子在设备的每个可旋转的头部之间保持连续接触,而一对径向端子仅在仪器头处于完全伸出位置时才电接触。 当仪器头旋转到关闭位置时,径向端子脱离以打开仪器头部中的照明源和装置内的电池源之间的电路。
