    • Apparatus and methods enable robust, reliable control for implantable medical devices, including cardiac pacemakers, defibrillators and cardiac resynchronization devices. Integrated circuits in the devices have minimized interfaces, can derive power from the interface signals, and have high voltage and latch-up protection. A device lead has a power generation circuit and a switching circuit using cascaded PMOS transistors for operating with a stable voltage despite fluctuations in the supplied voltage. The lead has control electronics that provide a very low impedance between an electrode and a lead conductor during most of the duration of a pacing pulse, but during a brief initial portion of the pacing pulse, provide a very high impedance to permit charging up a power supply that is local to the control electronics. A method of stabilizing the external impedance and a system for fault detection and fault recovery for an implantable device are also provided.

    • Methods and devices for determining the distance between a location emitting an acoustic, photonic, or electromagnetic waveform and a location detecting the emitted waveform are provided. In certain applications the emitting and/or sensing locations may be selected from within a human, mammalian, or animal body. The subject methods and devices find use in a variety of different applications, including cardiac resynchronization therapy. In certain aspects, a bioelectric signal pathway carries a pulse from cardiac pacing pulse generator to deliver a pacing pulse to a heart while protecting a bioelectric measurement device from interference from the pacing pulse.

    • This disclosure provides a handheld writing device and a related data entry system. In particular, a digital electronic clipboard is used to mount pages or forms utilized in forms processing applications, such as inventory tracking. A stylus having a writing tip at one end of the stylus and a bar code scanning mechanism at another end of the stylus is used to enter data on the pages or forms and scan bar codes appearing on the pages or forms themselves, or on a separate item to be associated with the form. The system detects whether bar code data or stylus position data is being generated and causes its CPU to responsively process entered data. In an alternative embodiment, the system also permits generation of only one of stylus position data and bar code data at any given time. By providing a bar code scanner in the same implement as the stylus, the system permits a user to scan bar codes without having to replace the stylus or obtain a scanning implement; furthermore, scanning of a bar code on a preprinted form inherently provides a stream of stylus data with information to exactly reproduce a hardcopy form completed by the user, e.g., by combining an image of the preprinted form with entered stylus data.
    • 本公开提供了一种手持式写入装置和相关的数据输入系统。 特别地,数字电子剪贴板用于安装在表单处理应用中使用的页面或表格,例如库存跟踪。 在触控笔的一端具有写入尖端的触针和在触笔的另一端的条形码扫描机构用于在页面或表格上输入数据并且扫描出现在页面或表单上的条形码本身或单独地 与表单关联的项目。 系统检测是否正在生成条形码数据或触控笔位置数据,并使其CPU响应地处理输入的数据。 在替代实施例中,系统还允许在任何给定时间仅产生一个触针位置数据和条形码数据。 通过在与手写笔相同的工具中提供条形码扫描仪,系统允许用户扫描条形码而不必更换触笔或获得扫描工具; 此外,在预打印形式上扫描条形码固有地提供具有信息的手写笔数据流,以精确地再现用户完成的硬拷贝形式,例如通过将预打印形式的图像与输入的触笔数据组合。
