摘要： An ink-cooled thermal ink jet printhead has an efficient heat exchanger located on the back side of the printhead that eliminates the need for heat sinks. All ink flowing to the firing chamber goes through the heat exchanger. The geometry of the heat exchanger is chosen so that almost all the residual heat absorbed by the printhead substrate is transferred to the ink as it flows to the firing chamber. Additionally, the pressure drop of the ink flowing through the heat exchanger is low enough so that it does not significantly reduce the refill rate of the firing chambers. The heat exchanger can have one or more active heat exchanger sides. The heat exchanger has little thermal mass itself and significantly reduces the thermal mass of printhead by eliminating the need for a heat sink. This reduces the warm-up time of the printhead to a fraction of a second.
摘要翻译：一种墨水冷却的热喷墨打印头具有位于打印头后侧的有效的热交换器，其不需要散热片。所有流入燃烧室的油墨都经过热交换器。选择热交换器的几何形状，使得打印头基板吸收的几乎所有剩余热量在流到喷射室时被转移到墨水中。此外，流经热交换器的墨水的压降足够低，使得它不会显着降低燃烧室的再填充速率。热交换器可以具有一个或多个活性热交换器侧。热交换器本身具有很少的热量，并且通过消除对散热器的需要而显着地降低了打印头的热质量。这将打印头的预热时间减少到几分之一秒。

摘要： An inaccurate blood pressure (BP) measurement can result if a person is not thermally comfortable during a cuff BP measurement. For example, an inaccurate BP measurement can result if a person feels cold when his or her upper extremity that wears the BP measurement cuff is exposed to a low ambient temperature during a BP measurement. Although a person can wear thermally comfortable clothing, the person's upper extremity must be exposed to the ambient temperature during a cuff BP measurement. A cover, such as a fabric blanket, thermo-regulated blanket, electric blanket, plastic tube, etc., for a BP measurement cuff and/or for a person's upper extremity that wears the BP measurement cuff can improve the person's thermal comfort and can stabilize cuff BP measurements. In addition, warm or cool conditioned air with an appropriate level of humidity can be introduced into the cover to make the person even more thermally comfortable.

摘要： An activity detector worn on or in the vicinity of the waist detects hip-joint actions of the user, by using a proximity sensor in the activity detector to sense the separation between the activity detector housing and a body target linked by the hip joint. For example, when the housing of an activity detector adjacent to the lower abdomen incorporates one or more sensing plates of a capacitive proximity sensor, flexion, extension, abduction, or adduction of the hip joint can be detected as the separation between the sensing plates and the lower abdomen changes. Besides the lower abdomen, alternative body targets include the thigh, buttocks, etc. Besides capacitive proximity sensors, alternative proximity sensors include active infrared proximity sensors, imaging sensors, etc. The activity detector can also incorporate an accelerometer to obtain additional movement and orientation data, which can be combined with the separation data to detect more complex activities.

摘要： Accelerometer-based detection for controlling audio-reporting watches, resulting in button-free operation. A wristwatch can use an accelerometer to detect the orientation and/or movement of a user's wrist and subsequently activate audio time reporting, without requiring the user to find and lush a small button. For example, a talking wristwatch can use this method to automatically report the time whenever a user moves or orients his or her wrist to a natural position for listening. A position such as that in close proximity to the ear can additionally facilitate private listening without disturbing others. Furthermore, the wristwatch can report time using personalized audio time components that the user has previously recorded, so that reporting is in a custom voice or language. In such applications, accelerometer-based control of audio-reporting watches offers significant advantages over conventional means of control, particularly in terms of ease of use and durability.

摘要： A system for synchronizing data after they are collected and stored locally in sensor units in a distributed sensor system, so that wired or wireless communication is not required during a data-collection session. Each sensor unit has a local clock providing local-clock times before and after a data-collection session, and a data processor uses its local clock or a sensor unit's local clock as the reference to compute each sensor unit's time-scaling factor, which is the ratio of the elapsed reference local-clock time and the elapsed local-clock time. The data processor uses the time-scaling factor to convert each sensor unit's local-clock data-sampling times to the reference local-clock data-sampling times, and the data processor subsequently interpolates sensor data to approximate simultaneous sensor-data values at desired reference local-clock times. A physical-activity monitoring system can use this synchronization method to reduce the size, power consumption, and cost of the sensor units.

摘要： A wrist joint-action detector adapted to be worn on or in the vicinity of the wrist region of a forearm detects wrist-joint actions of a user by using a proximity sensor in the detector to sense the separation between the proximity sensor and a body target in the wrist region. For example, a sensing plate of a capacitive proximity sensor is placed in the proximity of the wrist region of the forearm and the wrist region of the hand linked by the wrist joint to detect flexion, extension, abduction, or adduction of the wrist joint by sensing separation changes between the sensing plate and the wrist regions. Alternative proximity sensors, such as active infrared proximity sensors and imaging sensors, can also be used. The changes in separation between the proximity sensor and the body target can also be used for detecting handwashing or for controlling a computing device.

摘要： Accelerometer-based orientation and/or movement detection for controlling wearable audio recorders, such as wrist-worn audio recorders, resulting in button-free operation of the audio recorders. Operating a button-free wearable audio recorder does not rely on conventional switches that are often small, difficult to operate, and not very reliable. A wrist-worn audio recorder can use an accelerometer to detect the natural orientation and/or movement of a user's wrist and subsequently activate a corresponding audio-recorder function, for instance recording or playback, without requiring the user to remember to activate the audio-recorder function. In addition, a wearable audio recorder with a vibration mechanism can use this method to remind a user of an undesirable repeated movement, such as restless leg movement. In such applications, and many others, accelerometer-based control of a wearable audio recorder offers significant advantages over conventional means of control, particularly in terms of ease of use and durability.

摘要： A wearable joint-action sensor detects actions of a joint that links a first body segment to a second body segment by using a proximity sensor worn on the first body segment to detect a separation between the proximity sensor and the first and/or second body segment. Actions of a hip joint can be detected by wearing the joint-action sensor on the waist, and actions of a finger joint can be detected by wearing the joint-action sensor on a finger. A waist-worn joint-action sensor incorporating a proximity sensor for detecting hip-joint actions and a triaxial accelerometer for detecting body actions can detect common physical activities, such as sitting, standing, dancing, push-ups, and sit-ups, that cannot be detected by a prior-art waist-worn or wrist-worn pedometer. A detected joint action can also be used for controlling a computing device, or for reminding a user of poor posture or of sitting for too long.
