Utilization-based power consumption profiling in smartphones

Abstract: Energy cost of crowd-sourced continuous sensing is reported to be quite high. As the number of on-board active sensors increases, complications arise due to inter-sensor interactions. The energy-cost of the Smartphones is primarily due to wireless communications (in various modes, such as, cellular radio, GPS, Wi-Fi direct, and Bluetooth) and environmental sensing using its embedded sensors in a wireless personal area network setting. The existing popular on-device-online energy-cost profilers for Android Smartphones, namely, Amobisense and PowerTutor, are energy-hungry. In this paper, we report an efficient on-demand-online profiler, called pProf, that learns from offline-precomputed model parameters to reduce the online profiling cost. We have tested our proposed technique in a customized test-bed setup comprising of the Android Smart-phones with embedded sensors that also communicate with the neighborhood sensors on smart-wearables and Sensorcon's Sensordrone platform. Our experimental measurement studies demonstrate that, compared to the popular profilers, such as Amobisense and PowerTutor, pProf consumes typically 10–15% lesser energy.

Capturing a stable image using an ambient light sensor-based trigger

Abstract: A method and apparatus for capturing stable images are disclosed. An ambient light sensor makes measurements of ambient light. A change in ambient light between two measurements is determined. If the change in ambient light measurements falls in a predefined range, then the change may be attributable to ambient light sensor being blocked by a user to trigger image capturing. Consequently, a camera is triggered to capture an image. Conversely, if the change in ambient light measurement is outside the range, image capturing is not triggered as the change may be attributable to other factors.

eZaar, the smart container

Abstract: This paper is about an innovative way to make the food containers smarter in a kitchen. Many times it has happened with us when we are in the supermarket and fail to recall what's missing in our kitchen which we need to buy? Or we are too lazy to check every jar in our kitchen to know this before we plan a visit to store. eZaar, a Grain Drain Monitor, empowers us to know the amount of food inside our kitchen containers on the fly. It makes us realize what we are eating, our carbohydrate, protein, fiber, sugar, salt, caffeine/tea intake. It also tracks and control your dietary habits and does food budget planning. It can be tied up with a grocery ordering mobile/web app and export the list of things to be ordered.

Self-updating memory controller

Abstract: A system and method of making a firmware self updatable depending on option information stored in a configuration module. The configuration module can either be in a memory device or a memory controller. The self-updation flexibility can be achieved by customizing the options as per the customer's requirements and can be done either through an USB interface or by pre-programming the configuration module or any other communication or programming options. The option information is provided by using a configurable module inside either the memory or the memory controller. After the basic initialization operations, the firmware reads the option information from the controller itself or any other non-volatile memory and performs the tasks to enhance the overall performance.

Human footstep detection using proximity compensation algorithm withaccelerometer and time of flight sensor

Abstract: This paper is about an innovative and robust way to count human footsteps using accelerometer and proximity sensor (time of flight). The proximity compensation mechanism along with motion detection by accelerometer ensures to prevent false step detection. This solution can be used for smart shoe. Any shoe attached with this kind of solution will be smart enough to detect your step and calorie counts. When proper motion pattern is recognized by accelerometer, the time of flight sensor, on proximity to the ground, will detect a real step. Also this type of solution is going to help all those OEM/ODMs, who have introduced fitness bands for promotional purpose and providing rewards to the end user on daily/weekly step limit accomplishment.

Power Consumption Analysis, Measurement, Management, and Issues: A State-of-the-Art Review of Smartphone Battery and Energy Usage

Abstract: The advancement and popularity of smartphones have made it an essential and all-purpose device. But lack of advancement in battery technology has held back its optimum potential. Therefore, considering its scarcity, optimal use and efficient management of energy are crucial in a smartphone. For that, a fair understanding of a smartphone’s energy consumption factors is necessary for both users and device manufacturers, along with other stakeholders in the smartphone ecosystem. It is important to assess how much of the device’s energy is consumed by which components and under what circumstances. This paper provides a generalized, but detailed analysis of the power consumption causes (internal and external) of a smartphone and also offers suggestive measures to minimize the consumption for each factor. The main contribution of this paper is four comprehensive literature reviews on: 1) smartphone’s power consumption assessment and estimation (including power consumption analysis and modelling); 2) power consumption management for smartphones (including energy-saving methods and techniques); 3) state-of-the-art of the research and commercial developments of smartphone batteries (including alternative power sources); and 4) mitigating the hazardous issues of smartphones’ batteries (with a details explanation of the issues). The research works are further subcategorized based on different research and solution approaches. A good number of recent empirical research works are considered for this comprehensive review, and each of them is succinctly analysed and discussed.

User interface for camera effects

Abstract: The present disclosure generally relates to user interfaces. In some examples, the electronic device transitions between user interfaces for capturing photos based on data received from a first camera and a second camera. In some examples, the electronic device provides enhanced zooming capabilities that result in visual pleasing results for a displayed digital viewfinder and for captured videos. In some examples, the electronic device provides user interfaces for transitioning a digital viewfinder between a first camera with an applied digital zoom to a second camera with no digital zoom. In some examples, the electronic device prepares to capture media at various magnification levels. In some examples, the electronic device enhanced capabilities for navigating through a plurality of values.

Command aware partial page programming

Abstract: A method and system for partial page programming in a storage device is disclosed. An amount of data for partial page programming is determined. The amount may include host data (such as host data in a host command sent from a host device) and/or binary cache index data. The write step, used for partial page programming, is dynamically set based on the determined amount of data for partial page programming. In this way, the write step for partial page programming is dynamic rather than fixed. Further, dynamically setting the write step may reduce the number of programming steps for storing the host data in the host command and may reduce padding when partial page programming, thereby leaving less invalid data inside a block.

Digital viewfinder user interface for multiple cameras

Abstract: An electronic device has multiple cameras and displays a digital viewfinder user interface for previewing visual information provided by the cameras The multiple cameras may have different properties such as focal lengths When a single digital viewfinder is provided, the user interface allows zooming over a zoom range that includes the respective zoom ranges of both cameras The zoom setting to determine which camera provides visual information to the viewfinder and which camera is used to capture visual information The user interface also allows the simultaneous display of content provided by different cameras at the same time When two digital viewfinders are provided, the user interface allows zooming, freezing, and panning of one digital viewfinder independently of the other The device allows storing of a composite images and/or videos using both digital viewfinders and corresponding cameras
