Abstract: Sleep conditions such as moderate-to-severe sleep apnea can be assessed using a multi-night assessments. A respiration signal (e.g., acquired from a sensor strip) can be processed via a computing device. The respiration signal can be segmented and the segments can be classified to identify one or more apnea/hypopnea events. In some examples, some of the segments can be normalized such that each segment input for classification can be of the same size. The identified one or more apnea/hypopnea events can be used to estimate a nightly parameter indicative of a severity of (or presence of) sleep apnea. The nightly parameters from a multi-night period can be used to estimate a multi-night parameter indicative of the severity of (or presence of) sleep apnea. In some examples, quality checks can be performed to filter out some data (e.g., to exclude data from entire nights or exclude a portion of data from individual nights).

Abstract: A digital camera takes interleaved photographs of two different kinds. In one example embodiment, the first kind of photograph is taken using a first set of pixels of the camera's electronic array light sensor and has a short exposure time. The second kind of photograph is taken using a second set of pixels and has a long exposure time. More than one of the short-exposure-time photographs is taken while each long-exposure-time photograph is exposed. The two kinds of photographs are used for different purposes. For example, one kind may be used for performing automatic focusing while the other kind is used for displaying in a live view display. In this way, live view may continue while automatic focusing is performed. In another embodiment, one kind of photograph is used for providing a live view display, and the other is used in selecting exposure settings for a final photograph.

Abstract: Viewing devices are disclosed herein. One embodiment of a viewing device is a digital camera having at least one function. And embodiment of the digital camera comprises a touch pad, wherein in which a stylus that is moved relative to the touch pad is detectable by the digital camera. The speed at which the function is performed corresponds to the speed that the stylus is moved relative to the touch pad.

Abstract: A system and method for focusing an image capture device are disclosed. One embodiment is a method comprising moving an autofocus window in response to detected movement of the image capture device.

Abstract: A camera includes a light transmitter configured to transmit light pulses at a first rate, a light receiver configured to receive return signals corresponding to the light pulses transmitted by the light transmitter, and a sampler configured to sample electrical signals corresponding to the return signals received by the light receiver, wherein the sampler is configured to sample the electrical signals at a second rate that is lower than the first rate.

Abstract: A method and device for adjusting white balance are disclosed herein. The method may comprise generating data representative of an image with and without the use of a strobe. The contribution of the strobe and the contribution of ambient light are on the data are calculated. Based, in part, on the contributions of the ambient light and the strobe, a weight is calculated. The weight is applied to the data in order to adjust the white balance.

Abstract: Digital cameras and methods that provide for a rapid camera power-on sequence. A warm-sleep state is defined in which the camera and nearly all of its internal components are shut down, yet just enough information is retained within high speed volatile storage and processing units to rapidly return the camera to full operating state. The warm-sleep state is managed to consume a minimum amount of power to keep the vital information intact. Upon receipt of a power-on indication, the camera then transitions from the warm-sleep state to full operation by simply activating the processing units, and continuing operation from the state it was in immediately prior to the power-off request.

Abstract: A photography system includes a digital camera and a remote control. The remote control emits a light that the photographer can use to designate a subject to be photographed by pointing the remote control at the subject, casting a light spot on the subject. In a preferred embodiment, the light is generated by a laser pointer included in the remote control. The camera selects a region to photograph from its field of view, based on the location or motion of the light spot. The camera may optionally select a region that is centered on the light spot. The photographer may optionally specify the size of the region to be selected. The camera may optionally adjust the size of the selected region to assist in photographic composition. The camera may optionally be capable of making video recordings.
